The main difference between self-rising flour and all-purpose flour is that self-rising flour already contains baking powder and salt, which are essential leavening agents. This means that if you're using self-rising flour, you don't need to add extra baking powder or salt to your recipe - it's all taken care of. On the other hand, all-purpose flour is just plain flour, and you need to add your own leavening agents to get the job done.
Think of it like cooking a meal - if you're making a simple pasta dish, you can use a pre-made sauce (like self-rising flour), but if you're making a complex stew, you need to add your own spices and seasonings (like all-purpose flour). Both options are fine, but it depends on what you're trying to achieve. And let's be real - who doesn't love the idea of a quick fix or a magical solution that makes baking easier?
