I recently made a loaf of sandwich bread* whose recipe calls for 5 cups of
flour. (The loaf turned out great, btw). However, I got to thinking about
making it again, and this flour question came to mind.

When I make it again, I would like to add another flour, such as whole wheat
or oat, dividing the quantities of white flour and "Flour X" evenly, i.e.,
2.5 cups of each. Would I be able to use any other flour in equal amounts
for the recipe?

Thanks!
