For some reason, Wilton's recipe doesn't do well with off brand shortening & butter. I have tried Indydebi's BC recipe & didn't like it as well as I do the one I gave you. That recipe also does well with off brand shortening. You don't have to use Criso, most of the time I use an off brand all vegetable shortening. For an off brand, decrease the amount of half & half to 3 tbls. I don't know why but with the off brands, the batch turns out better if I cut back on it. Good luck!
