During the ‘war to end all wars’ the government rationed many items including heavy-duty soap chips, flakes, etc. Toward the end and shortly after the war was over, they okayed a 10 percent increase in the availability of soap making necessities but soap shortages persisted. Plenty of recipes were published but they called for fairly large amounts of grease. I wasn’t born until shortly after the war ended, but I can still remember that butchering a hog also included making soap. Here is the recipe for making one large bar of soap, including the correct proportions of ingredients that many homemakers used.
Mix and let cool 1/2 cup of soft water and 1/2 tablespoon of lye. When cool, add 1 tablespoon of borax and 1 tablespoon of ammonia. Pour into 1 cup of warm grease (pan drippings or rancid fat). Stir occasionally, until it develops a thick consistency. Pour into a cloth-lined mold. Let age, as it will whiten on standing.
