COOKING YOGURT RECIPES

Steps:

• Rub an ice cube over the inside bottom of a heavy pot to prevent scorching (or rinse the inside of the pot with cold water). Add milk and cream, if using, and bring to a bare simmer, until bubbles form around the edges, 180 to 200 degrees. Stir the milk occasionally as it heats.
• Remove pot from heat and let cool until it feels pleasantly warm when you stick your pinkie in the milk for 10 seconds, 110 to 120 degrees. (If you think you’ll need to use the pot for something else, transfer the milk to a glass or ceramic bowl, or else you can let it sit in the pot.) If you’re in a hurry, you can fill your sink with ice water and let the pot of milk cool in the ice bath, stirring the milk frequently so it cools evenly.
• Transfer 1/2 cup of warm milk to a small bowl and whisk in yogurt until smooth. Stir yogurt-milk mixture back into remaining pot of warm milk. Cover pot with a large lid. Keep pot warm by wrapping it in a large towel, or setting it on a heating pad, or moving to a warm place, such as your oven with the oven light turned on. Or just set it on top of your refrigerator, which tends to be both warm and out of the way.
• Let yogurt sit for 6 to 12 hours, until the yogurt is thick and tangy; the longer it sits, the thicker and tangier it will become. (I usually let it sit for the full 12 hours.) Transfer the pot to the refrigerator and chill for at least another 4 hours; it will continue to thicken as it chills.

Steps:

• Evenly coat the bottom of a medium Dutch oven or other heavy-bottomed pot with a thin, 1/4-inch-thick layer of water. (This will prevent the milk from sticking to the bottom of the pot.) Set the pot over high heat. Add the milk and heat until it just comes to a boil, watching closely: As soon as you start to see bubbles forming, take the pot off the heat. Let the milk cool until it reaches 130 degrees, 30 to 35 minutes. If you don’t have a thermometer, the milk should be warm enough that you can comfortably stick your (clean!) finger in it — it should feel hot, but not so hot as to scald your finger (think of a Jacuzzi).
• While the milk is cooling, smear the bottom of a 1-quart lidded glass, plastic or stainless steel container with 1 teaspoon of the yogurt. (A dab in the center is fine; you needn’t spread the yogurt evenly to coat the bottom.)
• When the milk has cooled to the proper temperature, add the remaining yogurt to the milk and whisk until the yogurt has completely dissolved into the milk, about 3 minutes. Pour the mixture into the prepared container and loosely set the lid on top, leaving a little room for air to get out.
• Place the container inside an unheated oven. Shut the oven, turn the oven light on and let sit for 2 hours (see Note). Check the yogurt: When it is done, it will be set (not liquid) but still jiggle like Jell-O. If it’s not yet set, leave it in the oven for 1 hour more. Depending on the temperature and humidity outside, the setting process can take up to 5 1/2 hours, so don’t fret if the yogurt isn’t done the first time you check.
• When the yogurt is done, top it with the lid to seal, and transfer the yogurt to the refrigerator to chill and fully set overnight before using. The yogurt will keep, covered, for 4 to 6 weeks. (It’ll start to get pretty sour after 2 weeks, which, depending on your tastes, could be a good or bad thing. You can also freeze a few tablespoons to start a later batch.)
