Why it works: Egg and butter 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 ↓
To Poach Eggs
Ingredients
Directions
Poach
Bring a stewpan of water to a boil.
Crack an egg into a cup and gently slip it into the boiling water.
When the egg white is set, use a slotted spoon to lift the egg out.
Serve
Serve the poached egg hot on toast with butter or on spinach.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Its proteins set with heat, holding the poached shape and giving the dish body.
- Butter
- Adds fat and richness that complement the soft yolk.
The step that matters
Lifting the egg once the white is set. Lift the egg only after the white has firmed. Lifting too early tears the delicate white, while the yolk stays runny inside a cooked outer layer.
Swap the spinach
The recipe marks spinach as optional. How well each one fits the dish's main ingredients (egg, butter):
- Asparagusfits better
- Chivefits better
- Leekfits better
- Spinachthe original
Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes.
