Red stamps were for meat, if you could find it, blue were for vegatables, fruits and beans.
That was kitchen common sense in 1942, when the U.S. Office of Price Administration froze certain prices and introduced the nation's homemakers to food rationing.
World War II brought shortages of gasoline, rubber, and much more. From then on the nation's coffee and sugar would go to the military first and civilians second.
War ration coupons and later tokens in 1944 became the cook's currency as women, who were in the majority of home kitchens then, learned to substitute and stretch. In lieu of a chicken in every pot, there was a Victory Garden in (nearly) every backyard. Good Housekeeping magazine's 1943 cookbook focused on making the best with less. And as cottage cheese came to replace meat in many recipes, sales rose from 110 million pounds in 1930 to 500 million in 1944.
