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 syrup
Combine water and sugar in a marbleized saucepan.
Boil for 10 minutes.
Test by dropping syrup into a bowl of water.
If 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.
Once cooled enough to touch, pull into sticks or a solid mass.
Make the molasses candy
For molasses candy, mix molasses and white sugar.
Boil until it snaps in water.
Add vinegar and baking soda, then stir well.
Pour and cool
Pour into greased platters.
Cool, using a knife to turn edges in for even cooling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Dissolves into syrup that sets into candy as its concentration rises during boiling.
- Molasses
- Adds dark color, deep flavor, and moisture to the finished candy.
- Cream of tartar
- Its acid helps keep the sugar from recrystallizing into a grainy texture.
- Vinegar
- Its acid partly breaks down sugar, keeping the candy smoother and softer.
- Baking soda
- Reacts with the acid to release gas, lightening the candy's texture.
The step that matters
Boil until it snaps in water. The candy's texture depends on how far the syrup is boiled. Too little leaves it sticky; too much makes it brittle. Testing in cold water shows the stage, so check often near the end.
