Molasses Candy

Ingredients

Directions

Prepare

  1. Combine molasses and brown sugar in a kettle.

  2. Butter a shallow tin pan.

Cook

  1. Boil over a slow, steady fire until done. Stir frequently.

  2. Test by dropping a little in cold water; if crisp, it's done; if stringy, it needs more time.

  3. Continue boiling until it stops bubbling.

  4. Add lemon juice just before removing from heat.

Cool

  1. Pour the mixture into the pan to cool.

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: ethanol (alcoholic, ethereal).

    Shared aroma: ethanol (alcoholic, ethereal).

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

Molasses
Provides the main sweetness, dark color, and rich flavor, and it sets firm as it cooks.
Brown sugar
Adds sweetness and a caramel-like depth, and helps the candy harden as it cooks.
Lemon juice
Adds acidity that helps keep the sugar smooth and prevents it from crystallizing.

The step that matters

Testing the candy in cold water. Sugar syrup changes quickly near the end of cooking. Removing it too early leaves a sticky, stringy candy, while cooking too long makes it brittle and can scorch the sugars.

Swap the lemon

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

  3. Figfits better
  4. Lemonthe original

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