Oooo sounds very promising!I have the Lemon and Vanilla Pudding. The Lemon Cream Wafer seems like it's the one. It's that lemon cookie part I was tasting in the original. I mixed it at 2% and like you, am pretty much convinced that's it. What it's missing is more lemon brightness and a whole lot of sweetness.
My tester with the Lemon flavor could possibly be the right one, but I think I over shot it at 2%. I'm going to try it lower and see what I think.
I was going to ger the Sweet Cream also and am mad I didnt.. O'well next time I guess. I haven't been this excited in a while!
