Why it works: Pepper and capsicum match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,571 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Cheese Paste Sandwich
Ingredients
Directions
Make the filling
Hard boil the eggs for 10 minutes, then place them in cold water to prevent discoloration.
Shell the eggs and mash the yolks finely.
Chop the egg whites and add them to the yolks.
Mix in salt, pepper, capsicum or chili, butter, and grated cheese. Beat the mixture well until combined.
Assemble
Spread the mixture on thin slices of buttered bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the bulk and rich, creamy body of the filling.
- Butter
- Adds fat and smooth richness, helping the filling spread.
- Grated cheese
- Adds savoury flavour and binds the mashed egg into a paste.
The step that matters
Cool the eggs in cold water right after boiling. Plunging boiled eggs into cold water stops the cooking quickly, which helps prevent the grey-green ring that forms around the yolk when overcooked eggs sit in residual heat.
Swap the capsicum
How well each one fits the dish's main ingredients (egg, pepper, butter, cheese, bread):
- Capsicumthe original
- Asparagusfits about as well
- Potatofits less well
- Tomatofits less well
Fit is the average pairing score against egg, pepper, butter, cheese, bread. Candidates are from the same food group and used in at least 100 recipes.
