Anonymous, Classic Variations in Cooking with Texas Eggs
“ There are various kitchen gadgets on the market which will separate eggs, but the most common method is to crack the egg in the center and shift the yolk from one half of the egg shell to the other, allowing the white to slip into a bowl and being careful not to break the yolk. Eggs are easiest to separate when cold, but whites reach their fullest volume if allowed to stand at room temperature for about 30 minutes before beating. ”
