I really like Fudge Sauce on ice cream. This Retro Ad & Recipe for 1-2-3 Fudge Sauce is from Carnation Evaporated Milk, September 7, 1953. You can follow the recipe, or you can make your own. I just love these vintage ads, don't you? So here's a way to beat the heat! I would use 4 squares, of course.. and probably substitute some excellent artisan chocolate!
