Why it works: Pepper and lemon 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 ↓
The Best Way to Cook Spinach
Ingredients
Directions
Prepare the spinach
Wash and pick the leaves from the spinach.
In a large kettle, add the spinach and sprinkle with salt.
Pour in boiling water and place the kettle over a brisk fire.
Shake or toss the spinach almost continually for 10 minutes.
Drain and chop the spinach very fine.
Finish and serve
In a saucepan, combine the chopped spinach, butter, cream, pepper, and salt.
Stir constantly until very hot.
Add the lemon juice, transfer to a hot dish, and serve immediately.

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; cooking and chopping soften it into a smooth, tender texture.
- Butter
- Adds fat and richness, giving the creamed spinach a silky mouthfeel.
- Sweet cream
- Adds moisture and richness, helping the spinach cling together into a creamy coating.
- Lemon juice
- Adds acidity that brightens the flavour and cuts the richness of the cream and butter.
The step that matters
Stir constantly until very hot. Cream and butter can separate or scorch if overheated or left unstirred, which would make the sauce grainy or give it a burnt taste. Constant stirring heats the mixture evenly and keeps it smooth.
Swap the spinach
How well each one fits the dish's main ingredients (butter, cream, pepper, lemon):
- Spinachthe original
- Potatofits about as well
- Asparagusfits about as well
- Leekfits less well
Fit is the average pairing score against butter, cream, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
