If you want to make frozen yogurt, presumably you’re expecting to use
yogurt for a good portion of your recipe. (It is the “yo” in fro-yo,
after all.) The problem is that yogurt, while creamy when you spoon it
from the carton, actually contains a good amount of water and not a lot
of fat. When you freeze it, the water forms crystals that make fro-yo
icy and decidedly non-creamy. The water also makes it challenging to
freeze yogurt into something that’s actually scoopable and not just a
solid ice cube. While there are a few ways you can solve this dilemma
(like hanging the yogurt in a cheesecloth overnight), in the end I
decided to just embrace plain yogurt and turn to a few cooking tricks to
ensure a spoonable creamy, and totally satisfying dessert.
