Self-Rising vs Regular Flour - Can I Use Regular?

Yes, BeijingRose, the baking powder in the self-rising flour is why you get such good “puff”.

Plain flour won’t puff on its own.

I always use self-rising as it puffs up a little better and makes the croquettes more lightly crispy. You can try it with plain flour if you want, but I cannot answer for the results. I also use self-rising flour in my latkes and it works perfectly. Thanks for asking!

No, unfortunately you can’t use them interchangeably. Self-rising flour has baking powder and salt in it. Flour is simply flour.

But there are any number of recipes for making your own self-rising flour on the web. Just google for one.
