If you have a favorite recipe that calls for all-purpose flour, you may be wondering whether you can replace it with Khorasan flour. The short answer is yes, but you should not always make the substitution as a simple one-to-one swap. Idaho Ancient Grains specifically recommends using about 25% less Khorasan flour when substituting it into regular recipes because Khorasan absorbs water readily. The amount may then be adjusted gradually if the dough or batter needs more flour.
