Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the dish, giving it body and a starchy structure once set.
- Eggs
- Bind the mixture and set on baking, giving the pudding its custard-like structure.
- Cheese
- Melts and browns on top, adding savoury flavour and a golden crust.
The step that matters
Grate cheese thickly over the top and bake until browned. Cheese grated thickly melts without fully drying out, and browning depends on the surface reaching a high enough temperature. Baking too long can dry the custard underneath.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, mustard, ketchup, cheese):
- Capersfits better
- Tarragonfits better
- Celeryfits better
- White pepperthe original
Fit is the average pairing score against egg, mustard, ketchup, cheese. Candidates are from the same food group and used in at least 100 recipes.
