Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main body of the topping, with whites setting when boiled and yolks adding richness.
- Melted butter
- Adds fat and richness, giving the egg mixture a smoother, silkier mouthfeel.
- Warm milk
- Moistens the chopped egg whites, loosening them into a softer, spreadable texture.
The step that matters
Boil the eggs for 15 minutes. Eggs boiled this long cook fully through, so the yolks become firm enough to rub through a sieve. Undercooked yolks would stay runny and fail to crumble into a fine texture.
