Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Buttered Eggs
Ingredients
Directions
Prepare
Break eggs into a bowl and add salt and pepper, then mix well.
Weigh butter and divide into two equal portions, cutting one portion into small pieces.
Cook
Place the other portion of butter in a small saucepan over low heat.
Pour the egg mixture into the saucepan and whisk continuously until it begins to thicken.
Add the small pieces of butter one by one, stirring constantly until the eggs are lightly set.
Add velouté, milk, or cream if desired.
Remove saucepan from heat and serve the buttered eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a soft, creamy structure as they thicken with gentle heat.
- Butter
- Adds richness and a smooth, velvety texture while keeping the eggs moist.
The step that matters
Add the small pieces of butter one by one, stirring constantly. Egg proteins set quickly over heat and can curdle or scramble if the mixture gets too hot. Adding butter in small pieces while stirring lowers the temperature and keeps the eggs smooth and creamy.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (egg, pepper, butter, milk):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Tomatothe original
Fit is the average pairing score against egg, pepper, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
