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 ↓

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 mould and, once packed and dried, holds its shape when inverted.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel to the spinach.
- Hard-boiled eggs
- Provide a mild, creamy contrast in flavour and texture as a topping.
The step that matters
Beat and toss until nearly dry. Spinach holds a lot of water, and excess moisture makes the mould loose and soggy, so it may not hold its shape when inverted. Cooking off the water while tossing with butter helps it pack firmly.
