Lemon Taffy

Ingredients

Directions

Make the taffy

  1. In a saucepan, combine sugar, water, and cream of tartar.

  2. Boil the mixture until it forms hairs or becomes brittle in cold water.

  3. Pour the hot mixture into a shallow buttered pan.

Flavor and work

  1. Once cool enough to handle, add tartaric acid and lemon extract.

  2. Work the mixture until evenly distributed, but do not overwork to maintain transparency.

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.

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

    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
Forms the bulk of the candy and sets into a glassy, chewy texture as it cools.
Cream of tartar
Acid that helps prevent sugar from recrystallizing, keeping the taffy smooth rather than grainy.
Tartaric acid
Adds a sharp, tart bite that balances the sweetness of the sugar.
Water
Dissolves the sugar so it can be cooked into a syrup without burning.

The step that matters

Work the mixture until evenly distributed, but do not overwork to maintain transparency.. Continued working of cooling sugar introduces air and promotes crystal formation, which turns taffy opaque and grainy. Stop once the flavorings are evenly mixed.

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.
