how to make a thicker yogurt

Making thick yogurt in an instant pot

thicker yogurt:1
thicker yogurt:2whole milk powder
I like to make yogurt in my instant pot but I find it can be a little runny. One recipe suggested adding powdered milk. I added 1 cup of powdered milk to about a gallon of milk and the finished product was thicker. Yay!

I have something that worked better. I didn't add the whole milk powder. Instead I added about a tablespoon or two to the whole milk I used. The yogurt was nice and firm and the taste was better.
