Blanket Tripe refers to the smooth tripe from the first stomach of the cow or ox which is considered to be the finest of the three (3) types of tripe from the cow or ox. The other two (2) are Honeycomb and Thick Seam Tripes. The first of the cows stomach is the "Banket" Tripe or the Rumen which is the largest part and holds up to 50 gallons of partially digested food. Good bacteria in the Rumen helps soften and digest the cows food and provides protein for the cow. Blanket Tripe is also known as Plain tripe.
