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

What each ingredient does

Potatoes: Provide starchy bulk that softens and gives the chowder body.
Flour: Thickens the milk broth into a smooth, creamy consistency as it heats.
Milk: Forms the creamy liquid base that the flour thickens.
Butter: Fat that softens the onion and carries flavor into the base.
Processed cheese: Melts into the hot liquid to add richness and a smooth, creamy texture.

The step that matters

Adding the flour mixture to the hot vegetables. Flour clumps if it hits hot liquid unblended. Mixing it with a little cold milk first and stirring constantly while adding it keeps the thickening smooth.
