Everyone should know how to boil an egg, it’s a cooking basic right? Or maybe not. Several years ago in Hawaii I wanted to boil some eggs for tuna salad. I suddenly realized that whenever I’d done it at home, I had a nifty little boiled egg timer that my mom used. With no timer, and no money to buy one, I turned to the one source I knew could tell me how long to boil an egg. I called my mom!
