Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Provides rich fat and body, giving the sauce a smooth, velvety texture.
- Milk
- Adds liquid that forms the base of the sauce and mellows its flavour.
- Cornstarch
- Thickens the boiling liquid into a smooth sauce as its starch swells with heat.
- Cold boiled potatoes
- Form the body of the dish, absorbing the sauce and becoming tender as they heat through.
- Butter
- Adds richness and a silky mouthfeel to the finished sauce.
The step that matters
Adding the cornstarch mixture to boiling liquid. Cornstarch must be fully suspended in cold liquid before it meets heat, or it clumps. Once the boiling cream and milk thicken it, the starch gelatinises and the sauce sets smoothly. Boiling briefly ensures the starch has fully swollen and the raw starch taste is gone.
