All-purpose flour typically has a protein content of 10–12%, which creates moderate gluten. That’s perfect for chewy cookies and sturdy breads.
Self-rising flour trends lower, around 8–9%. Less protein means less gluten, which equals tenderness. That’s why your grandma’s biscuits were so fluffy they practically floated.
If you are gluten-free, swap your all-purpose gluten-free blend and add the same baking powder and salt. The principle holds: flour + lift + salt = happiness.
Fun Fact That Impresses No One but You
The first commercial self-rising flour was created in England in the 1840s by a baker named Henry Jones. He wanted sailors to have fresh bread at sea without carrying separate ingredients.
So every time you use self-rising flour, you’re sharing a tiny bit of history with a 19th-century maritime baker. That’s unexpectedly charming, right?
Plus, you can now tell people you’re “maritime baking” when you skip the extra measuring. They’ll think you’re very cultured.
