Three-Ingredient Frozen Yogurt |
Commercial frozen yogurt may seem smoother and creamier for a variety of reasons. Many add cream. Others have gelatin, guar gum, carrageenan, or agar agar for thickness. The lower the fat content of a frozen dairy dessert, the more tiny ice crystals can form; some low fat brands of ice cream contain ice structuring proteins "borrowed" from fish to prevent the formation of these crystals. I have not encountered these proteins on the labels of frozen yogurt yet but it would not surprise me.
None of those magical additives are in here, so expect something more like a sherbet. I started with a firm yogurt made with whole milk using my favorite culture. The yogurt was given a day in the fridge to "set" before we used it.
