Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Poached Eggs and Spinach
Ingredients
Directions
Prepare the spinach
Wash the spinach well in several waters and remove the stalks.
Place the spinach in a large saucepan with enough boiling water to prevent burning and sprinkle with a little salt.
Boil uncovered until tender, then press out all the water.
Chop the spinach finely or rub it through a wire sieve.
Return the spinach to the saucepan with the butter, pepper, and lemon juice. Stir until very hot.
Poach the eggs
Toast a round of bread and cut it into triangles, arranging them around a hot vegetable dish.
Place the spinach in the center of the dish.
Fill a frying pan with water and bring it to a boil, adding a little salt. Remove the pan from heat.
Slip in the eggs (previously broken into a cup). Simmer until the whites are set.
Carefully remove the eggs with a slotted spoon. Lay the eggs on the spinach. 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 bed that the eggs rest on and carries the main flavour of the dish.
- Eggs
- Set when heated, so the whites form a tender coating around the yolk.
- Butter
- Adds richness and a smooth, silky texture to the cooked spinach.
- Lemon juice
- Adds acidity that brightens the flavour of the spinach.
- Bread
- Toasted triangles add crisp contrast to the soft spinach and eggs.
The step that matters
Simmer the eggs gently until the whites are set. Water at a hard boil breaks eggs apart, while gentle simmering lets the whites set around the yolk so the egg holds its shape.
Swap the spinach
How well each one fits the dish's main ingredients (butter, egg, lemon, pepper, bread):

- Shallotfits about as well
Fit is the average pairing score against butter, egg, lemon, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
