Here’s a shocking fact: Self-rising flour is a ticking time bomb. Not literally, but the baking powder starts reacting with moisture the second you mix it. Store-bought self-rising flour contains a special “low-moisture” baking powder that lasts months.

Your homemade version? It’s a one-night stand. You can store it in an airtight jar for a week or two, but after that, the puff-power fades. So only make what you’ll use. Unless you enjoy deflated, sad pancakes—then go wild.
Pro tip: Label your jar with a sharpie and the date. Otherwise, in three weeks you’ll find it and think, “Did I put cocaine in here?” No, you didn’t. It’s just old flour. Don’t be a hero.
