Ingredients
- 1 qt whole milk
- 1 Tbs plain yogurt with live cultures
- (Optional) vanilla
Directions
- Gently heat your milk to at least 180 F. Then, allow to cool to about 105-110 F.
- Take some of the warmed milk and mix with the plain yogurt to form a loose slurry. Stir this slurry through your milk until well combined.
- Put 1-2 C water in the bottom of the Instant Pot basin and insert your trivet. Fill your cooking container(s) and place on your trivet. Put a sheet of foil over the top to keep condensation out.
- Place a glass lid (or use regular lid with vent OPEN) on the Instant Pot and turn on the yogurt setting. Yogurt takes 8 hours.
- You will likely want to chill the yogurt overnight when it’s done so it will set properly. It thickens after cooling.
Notes
- I liked the vanilla flecks in the Siggi’s vanilla honey flavor, so I stirred a teaspoon of Nielsen-Massey vanilla paste into my milk
- When you heat the milk, you aren’t “sanitizing” it; you’re denaturing the proteins. DO NOT SKIP THIS STEP.
- The longer you incubate, the more tart your yogurt will be. It will set in 8 hours but you could as long as 12.
- I haven’t tried it yet but apparently the heating step can be done in the IP:
- Pour in your milk
- press the YOGURT button until it says BOIL
- Check temp with a thermometer and turn off the pot
- I haven’t done this mainly because I don’t want to wash out the pot so I can then use it for yogurt. However, I suppose it ultimately all comes to the same thing.
- RATIO: 2 (two) Tbs starter per 1 (one) gallon of milk
- Just tried it with half and half and it didn’t set. Rebatching to see if it sets; going with cold start (I already cooked the milk once). I’ll have to check the temp to see when it reaches 110, may also shoot for a 10-12 hour incubation.
- Rewatch seems to have set fully by 6 hours. Differences: first was poured into individual containers (uneven distribution of starter?); starter from first batch was from the more watery section of the yogurt. Second batch was incubated in a 4C Pyrex; made sure to take starter from the thicker part clinging to the top of the yogurt jar.
