I had read that people used to make their own baking powder and scoffed at those who purchased it, rather than baking “from scratch”. I never bothered to track down what they did. Apparently, it’s a “thing”, again – 150 years later. I found this video very interesting:
Adam Regusea is good – if you ignore his virtue signaling politics. He’s not a real lefty. As soon as his kids enter school, I bet he’ll drop the shibboleths like a hot potato. Anyway…
I have a snickerdoodle recipe that calls for Cream of Tartar and Baking Soda. I noticed that “hey, that’s old-school baking powder” when making a batch and thought to myself, I thought, “I bet I get a better rise if I use modern baking powder.” So I did.
I had two open containers in the pantry, so I grabbed the smaller one (to finish it off) and used that. I only noticed that it was Rumsfield baking powder as I put it away. We shall see what happens; the dough is still in the refrigerator.
