Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the custard that sets when baked.
- Eggs
- Set when heated, giving the custard its firm, sliceable structure.
- Sugar
- Adds sweetness to the custard, balancing the eggs and milk.
- Pie crust
- Holds the liquid custard in shape while it bakes.
The step that matters
Bake until set. Eggs thicken as their proteins heat and bond; underbaked custard stays runny, while overbaking can make it curdle or weep. Check that the centre barely wobbles.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, egg, lemon, sugar):
- Cinnamonfits better
- Nutmegthe original
- Dillfits less well
- Gingerfits less well
Fit is the average pairing score against milk, egg, lemon, sugar. Candidates are from the same food group and used in at least 100 recipes.
