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

What each ingredient does

Rice
Forms the body of the snow balls, becoming soft and tender when boiled.
Egg yolks
Thicken the custard and add richness as they set during gentle cooking.
Sweet milk
Forms the liquid base of the custard and adds creaminess.
Corn starch
Thickens the custard so it coats the rice rather than running off.

The step that matters

Cooking the custard until thickened. Egg yolks and milk can curdle or turn grainy if overheated, while undercooking leaves the custard thin. Cooking gently while stirring keeps it smooth and lets the starch and yolks set properly.

Swap the lemon

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