Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Candy Making
Ingredients
Directions
Make the sugar syrup
Combine 1½ pints of water with 3½ pounds of sugar in a marbleized saucepan.
Boil for 10 minutes.
Test by dropping syrup into a bowl of water.
When it forms a soft ball, remove from heat.
If it is too hard, add water and boil again.
Add a pinch of cream of tartar to prevent crystallization.
Make the molasses candy
For molasses candy, mix 1 quart of molasses with 1 pound of white sugar.
Boil until it snaps in water.
Add 1 teaspoon of vinegar and a pinch of baking soda. Stir well.
Pour into greased platters.
Use a knife to keep edges turned in for even cooling.
Cool and shape
Let cool until you can touch it.
Pull into sticks or a solid mass.
Cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Dissolves into water to form the syrup that sets into candy and gives sweetness.
- Molasses
- Adds deep flavor, color and chewiness to the candy.
- Cream of tartar
- Acid that helps prevent sugar from crystallizing into grainy texture.
- Baking soda
- Reacts with the acid in the mixture to add lightness as it sets.
The step that matters
Testing the syrup stage by dropping it into water. Sugar syrup sets according to its temperature and concentration. Removing it too early leaves candy soft, while boiling too long makes it hard or brittle, so testing in cold water shows when it has reached the right stage.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
