Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they cook, thickening the sauce into a smooth, pourable texture.
- Milk
- Provides the liquid base that the egg proteins thicken into a creamy sauce.
- Sugar
- Sweetens the sauce and adds body to the custard.
The step that matters
Whisk until thick over the simmering water. Egg proteins thicken gently with heat, so the bowl should sit over water that is steaming rather than rapidly boiling, and whisking keeps the heat even. Too much heat can scramble the eggs into lumps.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, milk):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Allspicefits less well
Fit is the average pairing score against egg, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
