Mtnbkr occasionally makes biscuits. He's tried to recreate his grandmother's recipe. Not sure if he ever nailed it, but I've been party to some damned good batches of biscuits.
He, I think, uses lard.
I've made biscuits a number of times over the years and they've turned out OK, but anymore I'll just buy some of the frozen Grands biscuits and pop them in the toaster oven. They're about as good as anything that I can make on my own.
