On the other hand, all-purpose flour is like the trusty sidekick - it's great for most recipes, but it needs a little help from its friends (baking powder and salt) to make it truly shine. So, if you're using all-purpose flour instead of self-rising flour, you'll need to add those extra ingredients yourself. It's not rocket science, but it does require a bit of math.
Now, you might be wondering why you can't just use all-purpose flour and call it a day. The thing is, baking powder is what gives self-rising flour its rise (get it?). Without it, your baked goods might end up a bit, well, flat. And who wants that?
