In praise of Durum flour, from Brar Mills.
I've gone through at least 30 pounds of this Sher brand high extraction durum flour, from Brar Mills, that I've purchased from a local Patel Brothers grocery store. It's called "Fiber Wala." ("Wala" is the Hindi word for "suppIier" or "provider.") I assume it's at most Indian grocery stores in North America.
It's a true flour, not a coarse semolina. I've used it for loaf bread, but it's really best for flat breads, such as tortillas, chapatis, and thin pizza crusts. Durum, a yellow wheat, does not make as good gluten as red or white wheat. But, if you want a high extraction, high fiber durum for your Altamura/Pugliese bread, this is it. The label says "whole wheat", but I don't think it is 100% whole grain.
For those who want a more "white" flour (though this is still yellow in color), endosperm only, with a low fiber content similar to All Purpose flour, they make "Desi Style" durum. But I have not tried it.
