Self-raising flour, on the other hand, is a type of flour that's specifically designed to make baked goods rise. It's got baking powder already mixed in, which means you don't need to add any extra leavening agents. This makes it a total time-saver for recipes like biscuits, pancakes, and muffins.
But here's the thing: self-raising flour can be a bit of a wild card. Because it's got baking powder mixed in, you need to be careful not to overmix or overbake, or your treats will end up tasting soapy or bitter. And, if you're using a recipe that's designed for all-purpose flour, you'll need to adjust the ratio of flours to get the right texture.
So, why do we need two different types of flour in the first place? Well, it's all about history and tradition. All-purpose flour has been around for centuries, while self-raising flour is a more modern invention. Back in the day, bakers used to have to mix their own flours and leavening agents, which was a total hassle. Self-raising flour made things easier, but it also limited the versatility of recipes.
