Why it works: Sugar and molasses are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Make the candy

  1. Dissolve the sugar and glucose in water and cook to 252°F (122°C).

  2. Quickly add the molasses, stir, and cook again to 252°F (122°C).

  3. Remove from heat and add the baking soda and black walnut meats.

  4. Stir in the kettle until it starts to grain.

Shape and serve

  1. Pour onto a warm slab and scrape it up.

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

What each ingredient does

Sugar
Provides the bulk of the sweetness and the crystalline base that sets the candy's structure.
Glucose
Interferes with sugar crystallization, keeping the candy smoother and less likely to turn grainy.
Molasses
Adds depth of flavour and colour, and some moisture, to the candy.
Baking soda
Reacts with the hot sugar mass to create a lighter, more porous texture.
Black walnut meats
Contribute nutty, bitter-edged flavour and crunchy texture throughout the candy.

The step that matters

Stir in the kettle until it starts to grain. Stirring controls sugar crystallization. Stir too little and the mass stays glassy; stir too long after it begins to set and it becomes too hard to shape before it cools.

Swap the walnut

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

  1. Almondfits about as well
  2. Nutsfits about as well
  3. Beansfits about as well
  4. Walnutthe original

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