The things one learns from one's parents... My mother suggested that for roasting a brisket, it will be nice and tender if you pour a can of Coca-Cola into the pan before roasting. I tried it last night, and the results are truly amazing. No, there is no caramel-sugar taste, just delightfully tender meat. It is worth a try.
My father remembered something from his janitor days about using the same substance to clean porcelain or unclog toilet drains or something of the like, but chances are I am less likely to try this.
