Made sugar free Keto Yogurt last night!
Used fairlife milk mixed with some heavy cream.
Came out with zero yogurt "twang", which is fine for us, but if you want twang, you may have to use some regular whole milk, a twangier starter, or let it incubate longer.
Made 2 small batches, using "yq" as starter for one and "two good" as started for the other.
Let the starter and the milk/cream come up to room temperature separately for 1.5 hours, then mixed together.
Left the containers in the dehydrator overnight set to about 112°
Some people who don't have a dehydrator or instant pot, warm up their oven to 150-170 turn it off, and put the yogurt containers in it overnight with the light on.
Another option is to put jars of yogurt mix in a cooler and pour boiling water in up to about 2/3 the height of the jar.
Can flavor with protein powder, vanilla, cinnamon, berries, or sugar free syrup, when you go to eat it.
