Stir thinned "starter" into the milk.
If using an Instant Pot, position the lid on top and push the Yogurt button. Time should be 5-9 hours according to the level of tartness you prefer. If you are doing overnight, set the pot to finish when you wake up.
Incubate
If using a bowl, place the pitcher in a warm environment. Keep the temperature at a constant 100-110˚F level.
Instant Pot: Use “Yogurt” mode for 5-9 hours.Without Instant Pot: Keep at 100-105°F for at least 5 hours.
Check consistency—yogurt should hold its shape when spooned.
