Can all purpose flour and self rising be mixed?

Yes, all-purpose flour can be mixed with self-rising flour, but it's important to consider the leavening agents already present in self-rising flour. Self-rising flour contains baking powder and salt, so if you mix the two, you may need to adjust the amount of additional leavening agents in your recipe to avoid over-leavening. This blend can be useful if you want to control the texture and rise of your baked goods. Always check the recipe requirements to ensure the final product turns out as intended.
