Never Use Flavored Yogurt For Homemade Frozen Yogurt. Here's Why - Tasting Table

"However, you can easily make frozen yogurt at home with the help of that tub of plain old yogurt in your fridge, emphasis on the "plain"! In an interview with Tasting Table, Zac Young, owner of Sprinkletown Donuts & Ice Cream and TV personality on Food Network, explained why flavored yogurt is not actually the best option for homemade frozen yogurt."

"The flavor of some yogurts will be lost in the freezing process because, as Young said,"the flavor of yogurt can dilute as you make the base and freeze. If you use something like strawberry yogurt, you can reinforce the flavor with freeze-dried strawberry powder." When yogurt is frozen, its liquid or water-based components create ice crystals, which apart from an icy texture, also dull the flavor of flavored yogurt."

Frozen yogurt has become a popular alternative to ice cream and can be made easily at home from plain yogurt. Plain yogurt provides a versatile base to add flavors and mix-ins while retaining control over sugar levels. Flavored yogurts often contain added sweeteners and can lose intensity when frozen because liquid components form ice crystals that dull flavor and create an icy texture. Sugar helps prevent crystallization and contributes to creaminess, so sugar additions must be managed intentionally. Intensifying flavor with freeze-dried fruit powders, frozen fruit, or extracts produces stronger results than using pre-flavored yogurt.
