Can I Sub Cake Flour for All Purposeの基本情報から最新動向までをわかりやすく整理しました。

Don’t do this for chiffon or angel food cakes. Those are pure protein-light divas. They need exact low protein to lift. Subbing all-purpose turns them into rubbery pancakes. Sad rubbery pancakes. Trust me, I’ve cried.

Also avoid swapping for pastry flour in pie crusts. Pastry flour is a middle child. Cake flour is too weak for pie. You’ll get a crumbly mess that tastes like disappointment. Stick to the swap only for cakes that aren’t litigious about their texture.
