One of the few food memories I do have of my dad is his trying to make the perfect fried egg. He had supposedly been a cook at the start of WWII. But military mess food then was powdered eggs, ersatz coffee, canned and mystery C-rations covered in “chocolate.”
My sister and I were 7 and 5 respectively when he decided to show us he could cook breakfast in our newly renovated “modern” (for 1962) kitchen. He braved the spattering bacon and fired up a separate frying pan for the eggs. He put a pat of butter in to melt and was explaining about the difference between fried, sunny side up and over easy, boiled, poached and scrambled eggs.
Any line or short order cook will tell you that working the breakfast rush is a particularly miserable gig because every egg order is a “custom” order. Every diner has a personal relationship with his eggs, given his childhood experience. “Scrambled” can mean “scrambled wet” or “ scrambled dry.” “Lightly beaten” can mean where threads of the whites show in the yellow. “Sunnyside up” might mean with a set, cooked skin on top gained by putting the pan in a broiler or salamander for the last 5 seconds. But "over easy" always means: “no popping the yolk.”
