Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Taffy

Ingredients

Directions

Make the syrup

  1. Combine water and sugar in a saucepan over medium heat.

  2. Stir until dissolved, then add cream of tartar.

  3. Wipe down the sides of the pan with a damp cloth to remove crystals.

  4. Boil until it reaches the 'crack' stage.

Cool and shape

  1. Pour into shallow greased pans to cool.

  2. Sprinkle lemon extract on top.

  3. When partly cool, mark into squares with a greased knife.

  4. Alternatively, pour onto a greased slab and fold edges toward the center until cool enough to handle.

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 + creamtop 9% of all pairs

    Shared aroma: 2,3-butanedione (butter, sweet).

    Shared aroma: 2-nonenal (fatty, green).

    Shared aroma: acetic acid (sour, vinegar).

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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

Granulated sugar
Provides the sweet, bulk body of the candy once cooked to a syrup.
Cream of tartar
Acidity that helps prevent sugar from crystallizing, keeping the taffy smooth.
Water
Dissolves the sugar so it can be heated evenly into a syrup.

The step that matters

Wipe down the sides of the pan. Sugar crystals clinging to the pan walls can seed crystallization in the syrup, making the taffy grainy. Washing them down with a damp cloth keeps the mixture smooth.

Swap the lemon

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

  1. Vanillafits better
  2. Strawberryfits better
  3. Raspberryfits better
  4. Lemonthe original

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