I make SF jello from time to time. I've used the store brands with aspartame. I've also used plain (knots) jello favored and sweetened with STUR - (natural sweetener stevia). I like to dice it and add whipped cream. Sometimes I dissolve the jello in just enough hot water to get the job done, then pour it into my ninja blender with ice and a few tbsp. of HWC. It makes a frozen desert that tastes sort of like orange sherbet.
