Can I substitute all purpose flour for rice flour?

Question

I have a recipe for cookies that calls for 2 1/4 cups all purpose flour and 1/4 cup rice flour. Can I just use 2 1/2 cups of all purpose flour? Will that ruin them?

(They're called Shortbread buttons, if that helps)

Answer 1

Rice flour absorbs more liquid than wheat flour, so you will want to make sure you either cut down the amount of liquid in the recipe OR substitute between 1/8 - 1/4 more all-purpose on top of what it calls for.

Answer 2

I don't see any reason why not.  Rice flour does not contain gluten so it shouldn't change the consistency too much.

Answer 3

Your fine, just remember rice flour absorbs more liquid than all purpose so use a bit less water (only a table spoon or two)
