How to Make Yogurt
All you need to make yogurt is milk and a bacterial 'starter'. It's so easy a 2 year old can do it. Check out my little man Kenny stirring the milk. In this case our initial starter is store-bought Stonyfield Farm's Yobaby yogurt because that's what happened to be in the fridge. However you can use any yogurt that contains live, 'active cultures' which is a more socially acceptable way to say live bacteria. Now that I have done this successfully a few times, I use my own yogurt as a starter. As for the type of milk, you can use whole milk, low fat or no fat milk. You can use regular or organic, depending on if you want regular or organic yogurt . You can even use goat or sheep's milk. It makes no difference. I used 1% lowfat organic milk because once again, that's what happened to be in our fridge. Using higher fat milk makes richer, creamier, more delicious yogurt, however it's not in our family's current diet.
EQUIPMENT
If you have a yogurt making machine, that's great. However I hate to make it seem like you have to buy a special piece of equipment for this. You don't. It does help to have the following equipment on hand:- 2 large pots, one of which fits inside the other
- a food or candy thermometer that clearly shows temperatures between 100 and 200 degrees Fahrenheit
- cheesecloth (for Greek yogurt)
- colander or strainer (for Greek yogurt)
- 2 clean dish or hand towels
- a heating pad (optional)
RECIPE
This process will outline how to make both regular Danon-esque type yogurt and the thick and super creamy Greek style yogurt similar to Oikos or Fage brands found in stores. You have to make the regular yogurt first in order to make the Greek yogurt.- 1 gallon of milk
- 3 Tbsp of yogurt containing live cultures
1 gallon of milk = 1 gallon of thin yogurt or 6 cups(48 oz) Greek yogurtUse whichever quantity of milk makes sense for your level ofconsumption and inoculate with 3 Tbsp of yogurt regardless of milkvolume. The yogurt will keep for 10-14 days if kept in a sealed container in the refrigerator and not contaminated. In other words, do not eat directly from the container or stick your finger in it and you should be good for up to 2 weeks.
1/2 gallon of milk = 1/2 gallon of thin yogurt or 3 cups (24 oz) Greek yogurt
1 quart of milk = 1 quart of thin yogurt or 1 1/2 cups (12 oz) Greek yogurt
PROCESS
At this point you can remove the inner pot from the outer pot and set it on a hot pad or towel and let it rest until it reaches 110 degrees, which will take 30-40 minutes. If you are in a hurry, place the milk pot into a cold water bath to drop the temperature quickly. I fill my sink with cold water, place the milk pot in it and then stir the milk occasionally and it reaches 110 in about 5-10 minutes.
Once the milk is between 105 and 110 degrees, place your 3 Tbsp of starter yogurt in a small bowl. Add 1/2 cup of the hot milk to it and whisk it together until smooth. Then pour the yogurt/milk mixture into the hot milk and whisk thoroughly. Remove the milk from the cold water bath, cover it, and place in a nice warm spot for 7-8 hours.
After 7-8 hours in a warm spot, you should have solid, plain, white yogurt. There should be a little bit of clear yellowish or blueish liquid on top. That's just the whey and it's perfectly normal. The yogurt is now ready to eat or cook with. To make your own flavored yogurt simply mix with jam, jelly, honey, lemon, or fresh fruits.
