Always. Every time. For biscuits, pancakes, quick breads, and muffins. It’s a one-to-one swap. If a recipe calls for self-rising flour, use your homemade version in the exact same amount. No math headaches. Just scoop and mix. You’re not a replacement baker. You’re the original.
But avoid it for yeast breads. Yeast is a diva. It doesn’t like baking powder competing with it. That would be like inviting two DJs to the same party. Chaos. Stick with plain flour for sourdough and bagels. Save your self-rising mix for the easy stuff.
The Fun of Experimenting
Now you can break the rules. Try adding a pinch of sugar to your flour mix for sweeter baked goods. Or throw in some cinnamon. Or dried herbs for savory scones. You’re not just substituting. You’re inventing. You’re a mad scientist in an apron.
One last quirky fact: The first commercial self-rising flour was sold in 1845 in England. It was called “Self Raising Flour.” Why? Because raising sounded fancier than rising. So if a British person corrects you, say you’re using “self-raising” flour. They’ll think you’re posh. Then laugh because you know the truth.
