Has anyone used this before in their recipes. Namely, strawberry, raspberry, and peach. If so, how did it turn out?
No idea...are they alcoholic or non-alcoholic. I've used all sorts of different liquids in recipes and you have to be careful with sugar content. You may have to cut back on the sugar in the recipe to compensate for the sugar in the drink mix.
With WASC for example, if you use a high sugar liquid, you cut the additional sugar to 3/4 cup...I've taken it down to 1/2 cup when I use things like melted ice cream.
Too much sugar and the cakes tend to sink and or come out gooey.
I have used Daily's Strawberry Dacquri mix for the strawberry puree for my strawberry mousse and it turns out great. (Because I am too lazy to puree the strawberries and stain out the seeds!)
