Hey there, BigMama!
I think it almost doubles from the churning, so about 2 C
minimum yield would be about right, if I packed it in the containers I'm using, it would be 3/4 full and it's a 20 fl oz or 600ml container. I definitely get 3 to 4 servings out of it.
I think it would work fine with some yogurt (after all, I've tried it with Buttermilk as the major ingredient) but I do think the glycerine and the simple syrup are needed as the smoothing ingredients or it's just too icy, too hard. It's just scoopable enough with these proportions. I've been eying the Pineapple protein powder with the thought of some coconut milk (Pina Colada Gelato, yum!) as the base, and sprinkled with toasted coconut right at the end...
and I've been snapping up any good sugarfree Singles drink mixes I can find, it's SO convenient! So far, CL Raspberry and Peach Mango -- and a Cranberry Fuji Apple Tea (different brand, though). And heck, I think a Granita experiment is in the cards, who needs dairy? It's SUMMERtime! You go girl, and post results here (and so will I). BTW, we DO do July 1st, that's Canada Day. Usually falls on the same weekend, one of those rare occasions where we have a holiday at the same time as you'all.
I've given up worrying about outweighing the DH, me, at least for now. Stress is doing me in! Messing in the kitchen is my only effective therapy right now
Ta!
