Yogurt disaster and recipe
I guess I get to make yogurt again tomorrow!
Anyway, if anyone out there would like to try giving homemade yogurt a try, here's my recipe. It's really easy--hands-on time is only about 10-15 minutes, most of which is just waiting for your milk to heat to the proper temperature. Way cheaper than buying it all, too, especially if your family likes yogurt as much as mine does.
Makes 1 quart (1 L)
1/2 c. (125 mL) good quality commercial plain yogurt with live cultures, or 1/2 cup yogurt from previous batch
1 qt. (L) pasteurized whole milk, (nonhomogenized is best--good luck finding it. Let me know if you do. I use Parmalat or Dairyland.)
a candy thermometer (I just use a pocket thermometer)
Gently heat the milk to 180 degrees F, stirring often so it doesn't stick to the bottom. Cool quickly to 110 degrees by placing pot in sink of ice-water. Stir in yogurt and place in small, clean containers. (I find anything bigger than a 750 mL yogurt or 1 L Cool Whip container doesn't work as nicely. Or, you could place in a shallow glass, enamel, or stainless steel container.) Cover the container and place in a warm oven (110-150 degrees, but no warmer, or a gas oven with a pilot light. You can check your oven by putting a 110 degree glass of water in it for a while and testing it occasionally with the thermometer before you do this the first time.) Check after three hours, but I find the best results are usually between 5 and 6 hours. After a point, all it does is make more whey. However, every so often check yogurt and sop up whey with a paper towel (you can also pour it off and save it for other recipes, if there is a lot--like when I used that really cheap milk!) Depending on how hot your oven is, you can leave it for up to 12 hours. Yogurt is ready when you can tip it and it pulls firmly away from the side of the cup. Transfer to the refrigerator.
You can sweeten an entire batch of yogurt by adding honey and vanilla after you stir the live culture in with the milk, or smaller portions by stirring it into each individual container. I have also put fruit and honey in the bottom of a container before pouring in the culture, but found this made the yogurt very runny, so decided to do it after from now on!
If anyone out there gives this recipe a try, I'd love to hear about your adventures (or misadventures!)
Edit: I now use half-quart jars to make this in, and find it works great. Also, after switching to raw milk, I was finding the recipe was turning out watery and not setting properly, until I realized that too much cream was being skimmed off. I have had the best results with unskimmed milk from a Jersey-type cow. (These cows have a much higher fat content in their milk than Holsteins.)
