Explaining a frittata to a customer: "What is it?" he asked. "Like, an, uh, egg brick with some stuff in it." I offered. Sensing that this was probably not the most appetizing sales pitch, I quickly tried again. "It's basically an omelet, only baked in to a square, rather than folded in a pan." Better. He decided that he would buy a blueberry scone instead. Safe. And I had never described it to him as something you might use to build a chimney. Perhaps that helped too.
