The flavor team

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.

  1. Sugar + vanillatop 8% of all pairs

    Shared aroma: beta-damascenone (apple, rose).

    Shared aroma: ethyl isobutyrate (fruity, ethereal).

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Molasses
Provides the dark color, rich flavor, and most of the sweetness.
Granulated sugar
Adds sweetness and helps the cooked syrup set firm as it cools.
Butter
Adds fat that softens the texture and reduces stickiness.
Baking soda
Reacts with the hot syrup to add air, lightening color and texture.

The step that matters

Cooking the mixture to the hard stage. The syrup must reach the point where it hardens in cold water. Stopping early leaves the candy sticky, while cooking too long makes it brittle and hard to pull.

Swap the vanilla

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

  1. Vanillathe original
  2. Raisinfits about as well
  3. Figfits less well
  4. Applefits less well

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