Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Welsh Rabbit on Triscuit
Ingredients
Directions
Make the cheese sauce
Heat the milk in a saucepan until scalding hot.
In a separate bowl, mix the cheese, flour, mustard, paprika, and beaten egg.
Gradually add the hot milk to the cheese mixture, stirring continuously.
Cook slowly until the mixture is smooth and creamy.
Remove from heat and stir in the butter until well combined.
Serve
Heat the Triscuit crackers in the oven and pour the cheese mixture over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Imperial cheese
- Melts into the sauce and provides the main flavour and body.
- Egg
- Thickens the sauce as it heats and adds richness.
- Flour
- Stabilises the sauce so it stays smooth rather than grainy or separated.
- Milk
- Forms the liquid base that the cheese melts into.
- Butter
- Adds fat for a smooth finish and glossy texture.
The step that matters
Adding the hot milk gradually while stirring. Pouring the milk in all at once or letting the mixture overheat can scramble the egg and cause the cheese to clump or turn grainy. Adding it slowly and stirring constantly keeps the sauce smooth.
