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 ↓
Spinach Dressed with Egg
Ingredients
Directions
Prepare the spinach
Boil the spinach in plenty of salted hot water for 20 minutes.
Drain and press out the water, then chop finely.
Cook the spinach
Return the spinach to the heat with butter, sugar, salt, pepper, and nutmeg.
Cook until hot and smooth, then transfer to a deep dish.
Make the egg topping and serve
In a mortar, pound the yolks of the hard-boiled eggs until smooth.
Mix in melted butter, cream, and lemon juice to form a paste.
Spread the egg mixture over the spinach and garnish with sliced egg whites.

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, once cooked and chopped, gives it a soft, smooth texture.
- Butter
- Adds richness and a silky mouthfeel to the cooked spinach.
- Hard-boiled eggs
- Yolks are mashed into a paste that forms the creamy topping over the spinach.
- Lemon juice
- Adds acidity that brightens the rich butter and egg flavours.
- Sugar
- Adds a small amount of sweetness that balances the bitterness of the spinach.
The step that matters
Cook until hot and smooth. Spinach that is not drained and pressed well will stay watery and dilute the butter, so the dish turns loose instead of creamy. Pressing out the water before chopping and reheating keeps the texture smooth and concentrated.
Swap the spinach
How well each one fits the dish's main ingredients (butter, sugar, pepper, nutmeg, egg, cream, lemon):
