Is there a blend of flour that I can use to substitute for white rye or medium rye flour? I'm realize i'm probably out of luck with the white rye, but can I blend whole dark rye with bread flour or white wheat to simulate the medium rye? The reason I ask is because I'd like to make a rye loaf, but all the recipes I come across ask for either white or medium rye...neither of which I can find at the stores in my area. I know I can order some, but then that puts me off a good 1.5 weeks or so. Thanks!
