Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Granulated sugar
Provides sweetness and dissolves into the water to form the sauce base.
Corn starch
Thickens the liquid as its starch granules swell and gelatinize when heated.
Lemon juice and rind
Adds acidity and bright lemon aroma that balance the sweetness.
Butter
Adds fat for richness and a smooth, glossy mouthfeel.

The step that matters

Add the wet corn starch to the boiling mixture. Corn starch must be fully dispersed in cold water first, or it clumps when it hits hot liquid. The mixture needs to be boiling so the starch granules swell and thicken the sauce evenly.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, corn, butter):

Fit is the average pairing score against sugar, corn, butter. Candidates are from the same food group and used in at least 100 recipes.
