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 ↓
Spinach, an Entree
Ingredients
Directions
Cook the spinach
Cut each leaf from the stalk and wash the spinach well.
Place the spinach in a saucepan of boiling water, sufficient to cover it, and add a little salt.
Boil quickly until tender, about 30 minutes.
Drain the spinach and rub it through a sieve with a wooden spoon.
Add the butter and mix well.
Place the spinach on a dish and keep hot.
Poach and serve
Break the eggs separately into cups.
Poach the eggs in boiling water.
Carefully place the poached eggs on top of the spinach.
Arrange slices of toast around the spinach, points upwards.
Arrange browned macaroni all around the dish.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Forms the bulk of the dish and provides a soft base for the eggs.
- Eggs
- Proteins set with heat, giving a tender, firm texture when poached.
- Butter
- Adds fat that enriches the spinach and gives it a smooth, glossy texture.
- Browned macaroni
- Browning adds toasted flavour and crisp contrast to the soft spinach.
The step that matters
Poaching the eggs. Egg whites begin to set as soon as they meet hot water, so breaking each egg into its own cup first lets it slide in gently and keep its shape instead of spreading and tearing.
Swap the spinach
How well each one fits the dish's main ingredients (butter, egg):

Fit is the average pairing score against butter, egg. Candidates are from the same food group and used in at least 100 recipes.
