Why it works: Molasses and sugar 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 ↓
Old-Fashioned Molasses Candy
Ingredients
Directions
The book gives no oven temperature. The 250°F in the steps was added when the recipe was transcribed, as a starting point.
Make the candy
In a large saucepan, combine molasses, sugar, vinegar, and salt.
Bring the mixture to a boil over medium heat, stirring constantly.
Once boiling, reduce heat and let it simmer until it reaches the hard ball stage (about 250°F or 121°C).
Remove from heat and stir in baking soda.
Shape and serve
Pour the mixture onto a greased surface and let it cool slightly.
When cool enough to handle, pull the candy until it becomes light in color and firm.
Cut into pieces and enjoy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides the dark color, deep flavor and chewy body of the candy.
- Sugar
- Adds sweetness and helps the mixture reach a firm, hard-ball set when cooked.
- Baking soda
- Reacts with the hot syrup to lighten its color and create a porous, airy texture.
- Vinegar
- Adds acidity that helps prevent sugar from crystallizing too much, keeping the candy smooth.
The step that matters
Simmering to the hard ball stage. Cooking to about 250°F (121°C) sets the candy's firmness. Too little cooking leaves it sticky, while overcooking makes it brittle, so a thermometer helps.
