No. 1 durum wheat. For superb pasta by hand or machine. You can see our quality! Semolina is the essential ingredient for making authentic handmade Italian pastas. It contains an exceptionally high percentage of gluten, which is what makes a pasta strand stretch and not break apart when cooking. Bob's Red Mill uses only premium quality, pure Durum Wheat and grinds it to Semolina's traditionally sandy texture. Try our simple handmade pasta recipe on back of this package.

That's why we carefully stone grind our grains in the simple and traditional way used by discriminating millers since early Roman times. With all the sophisticated technology of recent times, no machinery has yet been developed that grinds grains quite as well as our flint-hard quartz millstones. The granulation produced by stone grinding is far superior and the cool temperature of the process preserve valuable nutrients that are lost in conventional, high speed milling methods. We stone grind the widest possible variety of grains into flours and meals on our century-old mills. We mix them into an astounding array of delicious flours, cereals, and pancake, muffin and bread mixes. We also have a line of gluten-free products that are made in a dedicated facility and exhaustively tested for purity. We add to the list continually, making our product line of healthy grain-based foods the most complete in the world. Delight you and yours today with our stone ground goodness and know that you're eating the finest grain products available anywhere. To your good health, Bob Moore.
