Small-Batch Instant Pot Yogurt

Use a quart of pasteurized milk and plain live-culture yogurt for a small refrigerated batch; results depend on the culture and temperature control.

Ingredients

• 1 quart (4 cups) pasteurized milk, preferably whole
• 2 tbsp plain, unsweetened yogurt labeled with live active cultures
• Ice and water for an optional cooling bath; neither goes into the milk

Instructions

1. Check equipment before starting. Use an Instant Pot with a working yogurt program and a food thermometer. Read the instructions for the exact model; this is not a pressure-cooking cycle. Wash the inner pot, lid, thermometer and utensils thoroughly, and use the manufacturer's cleaning or sanitizing directions rather than assuming a short improvised steam cycle sterilizes them.
2. Heat the milk. Put the quart of milk in the inner pot. Use the model's yogurt heating program, checking with the thermometer rather than relying on the completion beep. Reach 180-185°F; if the model instructions allow additional gentle heating, stir and monitor closely to avoid scorching. Hold off the heat for 5 minutes.
3. Cool before adding the culture. Remove the inner pot and cool the milk to 105-115°F. An ice-water bath around the outside of the pot can shorten this to roughly 5-10 minutes; cooling without it can take about an hour. Keep bath water out and check the milk temperature directly. Dry the outside and base of the inner pot before returning it to the cooker. Lift off any surface skin if desired.
4. Inoculate. Blend the 2 tbsp yogurt with a little warm milk in a clean bowl, then stir it into the pot.
5. Incubate under control. Use the model's yogurt incubation setting for 8-10 hours, with the milk maintained around 110°F within the 105-115°F range. Do not substitute Keep Warm, pressure cooking, an unmeasured oven or an unregulated cooler. If your equipment cannot maintain the required range, do not improvise this process. Discard any batch after loss of temperature control or failure to set; do not taste it or try to rescue it.
6. Chill promptly. At the end of incubation, transfer to clean shallow food-safe containers and refrigerate at 40°F or below. Chill without stirring for at least 4 hours; a longer chill can improve texture. For thicker yogurt, strain for 1-2 hours through clean cheesecloth set over a bowl inside the refrigerator.

Notes

• Whole milk generally gives more body; lower-fat pasteurized milk is an option. Do not use raw milk for this adaptation.
• A yogurt's brand name does not guarantee that a home batch will reproduce its texture or flavor. The culture, milk and heating history all matter.
• Use a fresh store-bought live-culture starter for each batch here. The saved claims about harmless low temperatures, indefinite timing extensions and a guaranteed number of reusable generations are not adopted.
• Read the credited yogurt guide and locate the correct model in Instant Pot's manual library. The linked guide was consulted for temperature and timing facts; these directions are independently written.
• Milk is an allergen. Check the starter for additives, including gelatin if avoiding animal-derived ingredients, and for cross-contact information.

Storage

Keep finished yogurt covered at 40°F or below and use within 3-4 days as a conservative household window. Start refrigeration promptly after incubation; the controlled culturing period is not permission to leave finished yogurt on the counter. Strain only under refrigeration. Do not judge a questionable batch safe by tasting it.
