I’ve just found this wonderful leaflet entitled “Fillings for Take-Home Pastry Shells” 8 Tested Recipes from Betty King. I think it’s probably from the the late 1950s, it’s definitely from before metrics started in 1966. On checking I’ve found out that unlike Margaret Fulton, the 1970s cooking queen, Betty King did not exist. She was just an entity created as a marketing tool….an attempt to fool all of the people all of the time….so nothing’s changed there. But tastes have changed since then so I’m not sure you’d want to actually make any of the fillings.
