It doesn’t matter if the eggs are white or brown, cold or warm. Place eggs in a single layer in a pot, add about an inch of water, bring to a vigorous boil, and cover. I’ve found that for six eggs in a 2-quart pot, that steaming for 5 minutes will give you firm whites and a warm runny yolk. Three minutes more will give you a soft, firm yolk. I usually put the covered pot with the eggs and water on the stove, turn the heat on high, and set the timer for 10 minutes. Perfect results, every time.
