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 ↓
Poached Eggs
Ingredients
Directions
Prepare
Fill a basin with boiling salted water, greasing the bottom to prevent sticking.
Break each egg into a saucer and slide carefully into the water.
Poach
Keep the water hot but do not boil.
When a film of white forms over the eggs, remove them to a hot dish.
Serve
Top each egg with a piece of butter and sprinkle with pepper.

Egg and pepper barely smell alike, yet cooks put them together in 50,580 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- The proteins in the white set in the hot water, forming a tender shape around the yolk.
- Butter
- Melts over the hot egg, adding richness and a smooth, savoury flavour.
The step that matters
Keep the water hot but do not boil. A gentle, steaming heat lets the egg white set evenly around the yolk. At a full boil, the water churns and tears the whites apart, leaving ragged, scattered eggs.
