Sudan Grass: A Lifesaver In July


July doesn't seem to be the best time for grass-fed cows... by this point in the year, the grasses and clover are dry and brown, parched from lack of rain and blasted by two weeks of 90-plus degree heat.

But my bovine friends need not fear, for they will be happily munching on fresh, green sudan grass next week. Sudan grass is a warm weather crop that is indigenous to (can you guess?) Eastern Africa.

Farmers who graze with sudan grass need to be a little careful, because it can be dangerous to cows when it's young, due to an overabundance of the cyanide and nitrates that make it grow. Additionally, if the grass is affected by drought and a sudden rainstorm appears, the same chemicals can show up and poison the cows.

For a farmer, making sure a grass-fed herd has access to pasture all year is a daunting proposition, and involves a lot of pre-planning. Hay needs to be grown, mown and baled. Warm weather crops must be planted weeks, sometimes months, in advance. Fences need to be put up and taken down, usually on a daily basis. Thinking of all the factors involved is like trying to solve a giant agricultural Rubik's Cube.

But the payoff can be enormous. Milk from pastured cows is demonstrably better for you - there are higher levels of fat soluble vitamins like A and D, not to mention omega 3 fatty acids, CLA's (the "good" cholesterol) and beta-carotene, which is what gives milk from grass-fed cows its delightful yellow color. What the cows eat affects the taste of their milk, as well - in my experience, pastured dairy cows produce sweeter milk than anything you will find in a grocery store.

I haven't tried it myself, but I think the cows are going to be delighted.

Raw Milk: Healthy or Hopeless?


As some of my intrepid readers will recall, a few weeks ago I went to visit a raw milk dairy in Pennsylvania, The Family Cow. It was quite interesting, to say the least, and I was impressed enough with their safety procedures that I purchased a half gallon of milk to try on my own.

One of the bits of the tour that most struck me was how fervently Roderick, the fifth generation farmer who gave me the tour, believes in the curative powers of raw milk. Indeed, this is something that has grabbed my attention whenever I have come across raw milk drinkers - they believe in the healthfulness, and indeed, in the "superfood" stature of raw milk, with a fervor bordering on religious faith.

But me, I am a skeptic in almost all things, and I was determined to find out what, if any, scientific basis these health claims have.

To that end, I picked up a little pamphlet at The Family Cow on the benefits of, as it proclaims, "Fresh Unprocessed RAW MILK - A Nutrient-Rich Whole Food," in the hopes that it would give me a bit of insight.

Based on the research of a dentist named Weston A. Price in the 1930's, the brochure's central thesis is as follows: "Mammalian raw milk is a complex, bioactive substance of time-tested ancestral origin, where all parts work together to create a nourishing and protective food." The chief argument here is that raw milk contains enzymes and micro-organisms that are destroyed during pasteurization, making milk more difficult to digest and removing all the health benefits they provide.

At first glance, the brochure has all the earmarks of a legitimate publication. It has prominent quotations from doctors and professors on the cover, and cites studies and books, including pictures from Dr. Price's 1939 tome Nutrition and Degeneration, which is essentially the Bible of the raw milk movement. "1939?" you might be thinking. "Isn't that kind of a long time ago?" Indeed it is. And as I look more closely at the quotations on the front cover, I see that they date from 1928 and 1929, respectively. The points are not stacking up in favor of the raw milk folks.

But let's move on to what health benefits, exactly, raw milk is supposed to provide. The brochure provides an exhaustive list, which leaves no stone unturned. Raw milk, it says, treats high blood pressure, obesity, diabetes, heart failure, infection, urinary tract infections, prostate gland swelling, psoriasis, toxic thyroid disease, gastric ulcers, Pelvic Inflammatory Disease, pulmonary tuberculosis, edema, stiff joints, muscular dystrophy, and worms, and prevents dental decay. In fact, in one case of raw milk therapy that they cite, raw milk was successful in treating a "large group of patients for which no specific disease could be found."

And let's not forget the various anecdotal evidence I have heard from drinkers of raw milk, including my tour guide at The Family Cow, who claimed that drinking raw milk prevented colds, staved off allergies, boosts general immunity, and in the case of one farm worker who receives dialysis, even helps with kidney problems.

All that, eh? At this point, I begin thinking rather uncharitably of snake oil salesmen.

I'm not trying to argue that raw milk has no benefits whatsoever, but I am inclined to continue to view these health claims with further skepticism until  I can delve into some research a tad bit more recent than 1939.

Kitchen Experiment #176: Homemade Yogurt


Continuing my string of dairy-product-making-attempts (some more successful than others, I must say...mozzarella continues to elude me), I tried my hand at yogurt recently.

The process is fairly simple... heat a quart of milk to 185 degrees, whisk in yogurt starter (or yogurt with live cultures, which is what I used), pour it all in a quart jar, and then do your best to keep your yogurt-to-be around 110 degrees for the next six to twelve hours, which is more difficult than one might think. In my case, I filled two more quart jars with boiling water, swaddled all of them in a sweater, stuffed them in the non-working oven in my camper, then continued to anxiously check on it every few hours like a new mother looking in at her sleeping infant.

For a first yogurt, I don't think it was too shabby. It has a pleasantly tangy flavor, which I prefer. It is a little thin for my liking - closer to a kefir consistency than yogurt, really - but absolutely fine mixed with granola, which is how I always eat it.

And why is that, anyways? I think my yogurt starter was a little too old, for one thing. The fresher the yogurt, the better, where live cultures are concerned. Also, Clare told me that she lets the milk cool a bit before adding the starter, since the high heat can kill the cultures. And next time, I'll probably use a strainer to catch all the little bits of scorched milk that settled to the bottom of the yogurt, because that's just kind of gross.

I'm a little stumped about what to do about the skin that develops on top of milk when you heat it, though. Do I just need to stand there, whisking maniacally until it's ready to pour? I'd really rather not, if there are other options. Any ideas out there?

In Which I Drink Raw Milk


As some of you may have gathered from previous posts, I'm pretty fascinated with the saga of raw milk. Who would think that a mundane substance like milk could be so polarizing?

I was feeling rather investigative last week, so I went up to visit The Family Cow, one of the biggest raw milk-producing dairies in Pennsylvania, if not the entire East Coast. I was shown around for a couple hours, had my innumerable questions answered with unending patience, and when I left, it was with half a gallon of raw milk clutched in my sweaty palm.*

I was curious, I must admit. I'd never had raw milk before, and health claims aside, I wanted to see if there was any justification for the assertion that raw milk just tastes better than its pasteurized counterpart.

The taste test was conducted in my tiny kitchen. In a very professional manner, I poured two jelly jars full of milk: The Family Cow's raw whole milk in one, Clear Spring Creamery's un-raw whole milk in the other.

The two milks both looked the same. They both had cream at the top of the cartons (being unhomogenized, that tends to happen), and both had the yellow tint of grass-fed dairy products. No major differences there.

In the taste department, however, I definitely preferred Clear Spring Creamery's product. Maybe I'm just biased, since I work there and all, but when I tried the raw milk, I detected a faint "barnyard" taste.** According to Mark, this might be due to the cows' diet - he said that some cows can have a taste to their milk that he described as "silage." If that is the case, then milk purchased later in the year might be missing that taste.

The question of raw versus pasteurized aside, some of the reasons a small, raw milk, grass-fed dairy would be better tasting than Piggly Wiggly's are pretty obvious. First, the milk is fresh - likely from the last week - instead of weeks if not months old. Second, the milk is from grass-fed cows, which gives the milk much more flavor, and can in fact have flavors specific to what the cows eat. Third, many small, organic dairies go for heritage breeds like Jersey cows, which have richer milk due to the higher butterfat content. Fourth, the milk is unhomogenized, which affects not only its taste but its digestibility. And last, you're dealing with the milk of a small herd of - depending on the farm - 50 to 300 cows, as opposed to the milk of thousands of cows being mixed together, which is what conventional dairies do.

To be fair, I was definitely comparing two pretty delicious products as it was. It might be an interesting future experiment to do a blind taste test between raw milk, pasteurized milk from a small organic dairy like Clear Spring Creamery, mass-produced organic milk from a grocery store (like Horizon), and a conventional grocery store brand milk. If I were to compare regular milk from a grocery store with raw milk from a (relatively) small dairy like The Family Cow, I have no doubt which I would prefer.




*I was feeling pretty confident about The Family Cow's cleanliness, given that I'd just been over practically every inch of their operation and asked plenty of detailed (and perhaps somewhat impertinent) questions.
**This reminded me of my friend Bin's assertion that colostrum***, when he tasted it, was like drinking "hot hay".
***Colostrum is the rich milk that cows produce for the first several days after calving, and which is considered vital for a calf's immune system and overall health.

Butter Is Better



I am happy to report my first (successful) attempt at making a dairy product in my tiny own kitchen!

Blog, allow me to introduce you to Butter.

If you're anything like me at all, butter is absolutely indispensable. I saute asparagus, I bake cakes, I create tart crust, I smear pieces of baguette.

And, fabulously, butter has to be one of the easiest things to make ever. Observe:

Take one cup of cream and let it sit out until it reaches 50 degrees F. At the same time, put a clean quart jar in the fridge.

Once the cream has reached the desired temperature, pour it into the quart jar and screw on the lid tightly. Then start shaking the dickens out of it.

The cream will start out like cream, then frothy. After a few minutes, without any warning, it will have a whipped consistency. Do not be alarmed. And do not stop shaking.

After another few minutes, again with no warning whatsoever, the contents of the jar will turn from whipped cream into a large yellow lump and some milky liquid. Ta-da! You have made butter. This entire process should take somewhere between 5 and 20 minutes.

Pour off the buttermilk and store in the fridge for a refreshing pre-bedtime drink. 
Pour cold water over the butter and shake to rinse, then pour off. Do this three or four times, until the water runs clear.
Knead the butter with your hands (or with a pair of spoons, if you're fastidious) to remove any remaining liquid. This is important, since leaving the extra liquid can make your butter spoil. Stir in 1/4 tsp. of kosher salt, if so desired.

Spread on a piece of bread and enjoy.
 


Note: Do not be alarmed by the taxi cab shade of yellow that is my butter. It is representative of butterfat from grass-fed cows, and is caused by high levels of Vitamin A and beta-carotene - the same reasons that eggs from free-range chickens have similarly, shockingly colored yolks.

The Great Raw Milk Debate


I've been asked a few times now several variations of the following questions: Do you get to drink raw milk on the farm? And can you get me some?

The answers are no and no. But the topic has come up often enough that I think it's worth discussing.

Raw milk is a topic that can be pretty polarizing. People feel strongly about it from both sides - from the public officials who cite it as one of the leading causes of dairy-related illness to the moms who drive for two hours to purchase it where it's legal. Since the FDA banned inter-state raw milk sales nearly thirty years ago, illegal raw milk sales have skyrocketed. Now, many raw milk lovers have to get their dairy fix using methods that more resemble a drug deal than anything, from joining secret milk clubs to buying their milk labeled as pet food.

The sale of raw milk is illegal in Washington, D.C. and in the state of Maryland, where the dairy is located. Hence, no raw milk for us. We milk straight into the pasteurizer, where the milk is pasteurized at the lowest possible setting, which some people believe makes a better-tasting milk than ultra-pasteurization, where milk is heated for just a couple seconds at extremely high heat.*

According to Clare, one of the biggest differences between our milk and store-bought variety is actually the fact that we don't homogenize our milk. Homogenizing milk is the process of breaking up the fat molecules so they stay suspended in the milk. If you let unhomogenized milk sit long enough, the fat drifts up to the top, creating a layer of cream with the milk underneath. (Check out the picture.) Clare believes that homogenizing not only makes milk harder to digest - she's had lactose-sensitive customers who can drink the farm's milk with no ill effects - but also ruins the taste.

Here's my two cents about the raw milk debate: cows are dirty, dirty, dirty creatures, and they have an unfortunate tendency to get manure all over themselves. When we milk, we dip the udders in disinfectant and clean them off before putting on the machines; we also use a filter to catch any pieces of dirt or hair or what have you that sneak in.

But mistakes happen. Just this week, one particular cow with a sick sense of humor took a huge dump on me right as I was getting ready to put the machine on her. It's entirely plausible that in a situation like that, manure could make its way into the milk supply... and it only takes a little bit to make people sick, if that little bit has some E. Coli hanging out inside. Hence, I am inclined to view some judicious pasteurization as a good thing.

Additionally, while many pro-raw milk folks tout the various health benefits that raw milk supposedly provides - benefits they say are destroyed by pasteurization - Marion Nestle goes to great lengths in her book What To Eat to explain that the jury is still out on those claims. According to Nestle, the body of scientific knowledge for raw milk benefits is somewhat shaky, with studies going both ways on the issue.

Which brings us to the question of taste. Having never tasted raw milk, I can't comment on how Clear Spring Creamery's milk compares. But I can say definitively that this farm's milk gives your average grocery store milk a good spanking every day of the week, and is the best milk I have ever - EVER - tasted. Frankly, I really don't see how raw milk could taste any better.

That being said, I feel that anyone seriously dedicated to drinking raw milk should go to great pains to research their suppliers. That means going to the farm, asking questions, getting a tour, meeting the cows, and so on. Raw milk buyers need to hold their suppliers to the highest possible standards if they want their dairy to be E. Coli-free.





*A quick pasteurizing tutorial: Pasteurization, named for Louis Pasteur who came up with the modern process in 1862, is the process of heating a food at a certain temperature for a definite length of time and then cooling it.
