The next time a recipe calls for self-rising flour and you don’t have it, just laugh maniacally. Because now you know the cheat code. You are a flour alchemist.
Just remember: 1 cup AP flour + 1½ tsp baking powder + ¼ tsp salt. Say it with me. Say it louder for the people in the back.
You’ve got this. Now go make something warm, buttery, and probably a little bit lopsided. That’s the best kind, anyway.
