Why it works: Pepper and mustard are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 15,430 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eastern cream cheese
- Provides the main cheese flavour and body of the filling once melted into the milk.
- Milk
- Loosens the grated cheese so it blends into a smooth, spreadable mixture.
- Eggs
- Bind the mixture and help it set as it cooks, giving the filling structure.
The step that matters
Let the mixture cool. Adding eggs to very hot cheese can scramble them and leave a grainy texture. Letting the mixture cool before spreading keeps the filling smooth and lets it thicken slightly.
Swap the mustard
How well each one fits the dish's main ingredients (cream cheese, milk, egg, pepper, bread):
- Capsicumfits better
- Asparagusfits better
- Potatofits better
- Mustardthe original
Fit is the average pairing score against cream cheese, milk, egg, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
