Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Their proteins set when heated, giving the yolk and white a firm, tender shape.
- Butter
- Adds richness and fat, carrying flavour and giving a smooth, silky mouthfeel.
The step that matters
Cook for about 4 minutes. Egg proteins set as they heat, so timing matters. Too short leaves the white runny, and too long makes the yolk chalky and the white rubbery.
Swap the spinach
