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

What each ingredient does

Turnips
Form the main body of the dish as the vegetable being cooked and served.
Corn-starch
Thickens the cooking liquid into a glossy sauce as it heats and boils.
Sugar
Adds sweetness that balances the savoury salt and pepper.
Young beets
Serve as the base that the thickened mixture is poured over.

The step that matters

Cook until it boils. Corn-starch only thickens once it reaches a boil, so stopping early leaves the sauce thin. Stirring it in before cooking also keeps it from clumping.

Swap the turnip

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

  1. Capsicumfits better
  2. Carrotfits better
  3. Sweet potatofits better
  4. Turnipthe original

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