Homemade Yogurt

After making 30-minute mozzarella last summer, I was sure that Ricki Carroll's Home Cheesemaking could lead me through any dairy magic I dared. All the hard cheeses still seem a bit too involved for my liking; but yogurt was so obvious I couldn't ignore it.

At least once a week, I bring home a quart of non-fat plain yogurt, in a plastic quart container. These are very handy for storage; but now I have a life-time supply. Sure, they are recyclable; but do I have to keep generating more?

My first attempt at yogurt gave me enough anxiety that I consulted the book and bought a commercial starter (YoGourmet packets, from the grocery store). The instructions didn't match exactly, but were close enough to let me know where the wiggle room lies. In short:

• Heat a quart of milk on the stove to 180 degree Fahrenheit.


• Let it cool to between 105 - 115 degrees.


• Mix in the starter.


• Pour into a Pyrex quart measuring cup.


• Keep warm (incubate at about 110 degrees), covered, for 4 - 6 hours.


• Chill, covered, in the fridge.

Notes:
You can use a couple tablespoons yogurt as your starter, instead of buying it.
My milk thermometer is a little espresso temp stick; any thermometer for liquids will do.
On my first batch, I incubated in the oven, which over-heated the yogurt. Tasted great - don't know if the heat killed the active cultures, though.
On the second batch, I wrapped the container in towels and kept in an unheated microwave. Maintained about 100 degrees, and tasted great. Set up fine, not quite so firm.
My whole milk batch was really rich, creamy and high-calorie.
My 2% fat milk batch was tangier, and a little thinner.
I used Pyrex for heat resistance and insulation. Other materials are probably fine, too.
* Good, fresh milk really helps. I use Clover, because it is local to me and humane-certified. Never, ever use ultra-high pasteurized - everything good has been cooked out.
