Earlier the same day with the exact same ingredients I made Southern Biscuits that gave me a yield of a dozen. That was my test batch, I needed three dozen so I went back to the same recipe and tripled all of the ingredients. By time I added the butter and shortening to the flour, baking power, baking soda, and salt (kosher) it looked and felt nothing like the first time (which was moist and like bread crumbs). Once I added in the Buttermilk it still had too much flour so I added a little more buttermilk and butter. Once the dough was the right consistency I rolled it out and began forming my biscuits to cook. Once done, on my... what a disaster... they were tasteless and the inside felt a little soft but not quite undercooked.
I'm very new at multiplying recipes, and I know my math was right because I double checked it online, but this batch was so horrible I didn't even want to torture my dogs with it, it just went straight into the trash. Any ideas why that happened?
