Forgot to mention one other thing. For those of you who have not tasted the Water Flavets from Capella's like the Blueberry Pomegranate, Orange Mango, etc., they are the same concentrated flavorings. The only difference is that they are sweetened with stevia.
I told Tom no hurry on the Cake Batter that someone on ECF had already come up with one. IIRC, it was 5 drops (62.5%) Cap's Vanilla Custard and 3 drops Cap's Caramel (37.5%); with Breaktru's calc @ 15% would be 9.4%/5.6%. They got a chuckle out of that.
