Making Plain Yogurt at Home
This is a simple exercise in patience and temperature control. Once you master the rhythm of heating and incubating, you stop relying on store-bought containers and start working with a living pantry staple.
The importance of hygiene and warmth
Ensure every spoon and jar is thoroughly cleaned and rinsed to prevent unwanted bacteria from competing with your starter. Your environment needs to stay steady at 110°F, so have a plan for keeping your vessel warm.
- Heavy-bottomed pot
- Instant-read thermometer
- Whisk
- Clean glass jars
- Insulated cooler or oven with light on
What goes in.
- 1/2 gallonwhole milk
- 3 tbspplain store-bought yogurt with live cultures
Denaturing the proteins
Bringing the milk to 180°F is non-negotiable; it breaks down the whey proteins so they can form a solid network, ensuring your finished product is thick rather than runny.
The method.
Heat the milk
Pour the milk into your pot over medium-low heat. Use a whisk to stir occasionally, scraping the bottom so the milk doesn't scorch.
Scald
Once the thermometer reads 180°F, remove from heat. Let it cool undisturbed until the temperature drops to 110°F.
Inoculate
Whisk a half-cup of the warm milk into the starter yogurt until smooth, then pour that mixture back into the main pot and whisk gently to combine.
Incubate
Pour the mixture into clean jars, seal them, and place them in a warm spot—like an oven with only the light turned on or a cooler filled with warm water—for 8 to 10 hours.
Chill
Move the jars to the refrigerator once the yogurt has set. Do not stir it while it is warm, or it will remain liquid.
Other turns to take.
Greek-style
After the yogurt has chilled overnight, line a colander with cheesecloth, pour the yogurt in, and let the whey drain into a bowl for two hours until it reaches your desired thickness.
When it doesn't go to plan.
If your yogurt is too thin, try heating the milk to 190°F next time to remove more moisture.
Save three tablespoons of your current batch to act as the starter for your next one.
Keep the incubation environment steady; drafts will slow down the bacteria and cause the yogurt to taste overly tart.

How do I know if it has gone bad?
Trust your nose. Good yogurt should smell fresh and mildly acidic. If it smells like yeast, mold, or shows any surface discoloration, discard the entire batch.
