Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites are chopped into the sauce for body, and sieved yolks add richness and a fine texture on top.
- Milk
- Forms the liquid base of the sauce, which thickens as it comes to a boil.
- Cornstarch
- Thickens the milk into a smooth sauce when stirred into it while boiling.
- Butter
- Adds fat and flavour to the sauce and helps the cornstarch blend in smoothly.
The step that matters
Stir the butter-cornstarch mixture into the boiling milk. Cornstarch only thickens fully when heated, and it clumps if added without being smoothed into fat first. Adding it to boiling liquid while stirring disperses the starch so the sauce thickens evenly.
