Why it works: Spinach and pepper are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,400 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Spinach in a Mould
Ingredients
Directions
Prepare the spinach
Carefully pick over the spinach, removing stems.
Boil the leaves in salted water for 15 minutes.
Drain and press out all the water.
Chop the spinach finely and return it to the saucepan.
Shape and serve
Add butter, powdered sugar, salt, and pepper; stir until hot.
Press the mixture into a mould that has been wet with hot water.
Carefully turn out onto a heated dish and garnish with slices of hard-boiled eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh spinach leaves
- Forms the bulk of the mold and provides the green flavor and body.
- Butter
- Adds fat and richness, giving the spinach a smooth, silky texture.
- Powdered sugar
- Adds a little sweetness that balances the earthy flavor of the spinach.
- Hard-boiled eggs
- Served as a garnish, adding mild richness and contrast in color and texture.
The step that matters
Press out all the water. Spinach holds a lot of water, and any left behind makes the mixture loose and watery, so it will not hold its shape when turned out of the mold.
