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 ↓
Greens, Spinach, Etc
Ingredients
Directions
Prepare the spinach
Pick over and trim the spinach, then wash it in five waters and drain.
Place the spinach in a kettle with the water that drips from it.
Cook and season
Cook slowly at first until the juice is drawn out, then cook quickly until tender.
Drain and rinse if you dislike the strong flavor, then chop the spinach.
Reheat the chopped spinach, season with butter, coarse sea salt, and pepper.
Add cream if desired, or serve with lemon or vinegar.
If serving as a course, garnish with hard boiled eggs or serve cold as a salad.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Forms the body of the dish and gives it its main flavor and texture.
- Butter
- Adds fat and richness, carrying flavor across the cooked leaves.
The step that matters
Cook slowly at first until the juice is drawn out. Starting low and slow lets the spinach release its own water gently, so it wilts evenly. Cooking hard from the start can scorch the leaves before the juices come out, leaving the spinach unevenly cooked and tough.
