Molasses Candy

Ingredients

Directions

Prepare

  1. If the molasses is impure, skim it when it first boils.

  2. Butter flat pans.

Make the candy

  1. Boil the molasses slowly until it reaches the hard crack stage; test by dropping some in cold water.

  2. For added brittleness, add a piece of alum or a teaspoon of baking soda.

  3. Optionally, flavor the candy.

  4. Optionally, mix in nuts or popcorn.

  5. Pour the candy into the pans to cool.

Finish

  1. When nearly cool, pull the candy until it turns white.

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

What each ingredient does

Molasses
Forms the candy base and, when boiled to hard crack, sets it firm and brittle.
Alum
Adds brittleness to the candy when included.
Baking soda
Lightens the texture and adds brittleness when included.

The step that matters

Boil the molasses to the hard crack stage. Hard crack stage means the sugar concentration is high enough that the candy sets firm and brittle when cooled. Stopping early leaves a soft, sticky result, while going too far can scorch the molasses and taste bitter.

Swap the nuts

The recipe marks nuts as optional. How well each one fits the dish's main ingredients (molasses, butter):

  1. Almondfits better
  2. Pecansfits better
  3. Walnutfits about as well
  4. Nutsthe original

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