Why it works: Butter and parsley are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 28,563 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Buttered Eggs
Ingredients
Directions
Prepare
Break the eggs into a bowl and beat them until light and frothy.
Melt the butter in a separate bowl over boiling water.
Cook the eggs
Combine the melted butter and beaten eggs in an enamelled saucepan.
Stir continuously over gentle heat until heated through, without boiling.
Occasionally transfer the mixture back to the bowl to ensure even cooking.
Prepare the toast while the eggs are cooking.
Serve
Once the eggs are hot, pour them over the toast and sprinkle with chopped parsley before serving.

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 mass that forms the body of the dish.
- Butter
- Adds richness and moisture, keeping the eggs smooth and silky as they cook.
The step that matters
Stir continuously over gentle heat without boiling. Egg proteins set and curdle when overheated, so gentle heat with constant stirring keeps the mixture smooth and creamy instead of grainy or scrambled.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter):
- Nutmegfits about as well
- Parsleythe original
- Capersfits about as well
- Tarragonfits less well
Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes.
