Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites and yolks add structure and richness to the mixture as it sets.
- Flour
- Starch from the flour thickens the cooked mixture and gives it body.
- Butter
- Fat adds richness and tenderness to the mixture.
- Milk
- Liquid that hydrates the flour and helps form a smooth mixture.
The step that matters
Stirring while the mixture boils. Flour starch must be cooked while stirring so it gelatinizes evenly and does not scorch or form lumps. The mixture is done when it pulls cleanly from the pan, showing the starch has thickened enough to hold its shape.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, milk, butter, flour, pepper):
- Nutmegthe original
- Cinnamonfits about as well
- Parsleyfits about as well
- Cardamomfits less well
Fit is the average pairing score against egg, milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
