The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Light brown sugar
Provides the sweetness and, as it cooks and cools, forms the crystals that give the frosting its body.
Sweet milk
Dissolves the sugar and adds moisture so the mixture can cook into a spreadable frosting.
Butter
Adds fat for a smoother, richer mouthfeel and softens the frosting's texture.
Vanilla extract
Adds aroma and flavor that rounds out the caramel sweetness.

The step that matters

Stirring after removing from heat. Overcooked sugar can set hard. Removing the pan at the right point and stirring as it cools encourages fine sugar crystals, which give a smooth, creamy texture rather than a grainy or stiff one.

Swap the walnut

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

  1. Almondfits better
  2. Cocoafits better
  3. Chestnutfits better
  4. Walnutthe original

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