I just love this old advertisement: "9 out of 10 doctors say: 'IT'S DIGESTIBLE!'" Cracks me up every time.... :-) But this last time I was flipping through my stacks of old women's magazines (which I love collecting), I also began craving biscuits. And as Saturday was a miserable, rainy day, this is how I spent my morning. I used this recipe, although because of our altitude, I doubled the amount of baking powder called for.
They turned out perfectly and neither Big Jim nor I felt any ill effects, so indeed it appears the Crisco IS digestible. Incidentally By the early 1950s, the ad copy dropped the "9 out of 10 doctor..." bit, but if you have doubts, you can always double the butter and eliminate the shortening, but I don't believe the biscuits will have the same flaky (which to me is critical) consistency.
