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

What each ingredient does

Flour
Thickens the sauce as it heats, giving it a smooth, body-rich texture.
Sugar
Adds sweetness and helps give the sauce its rich, syrupy character.
Maple syrup
Adds sweetness and a distinct syrupy flavor that defines the sauce.
Butter
Adds fat for a richer mouthfeel and a rounder, more savory-sweet flavor.

The step that matters

Mix the flour with cold water until smooth. Flour lumps form if it meets hot liquid directly. Blending it into cold water first disperses the starch evenly, so the sauce thickens smoothly when heated.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Jalapenofits about as well
  4. Gingerfits less well

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