今注目を集めている Can I Use Self Raising Flour Instead of All Purpose Flourについて、多角的な視点を整理して公開しています。

Here’s the deal: self-raising flour is not a magical twin of all-purpose. It’s all-purpose flour with a tiny, fizzy party inside. That party is baking powder and salt, already mixed in.

All-purpose flour is a blank slate. It waits for you to add your own leavening (like baking soda or powder). Self-raising is impatient. It wants to puff up right now.

Think of it like this: all-purpose is raw cookie dough. Self-raising is a cookie that’s already half-baked in the chemistry department.
