Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Molasses Solferino
Ingredients
Directions
Cook the base
In a copper pan, combine 2 gallons of molasses, 1 teaspoon of cream of tartar, and 3 pounds of glucose.
Set the pan over medium heat and stir until the mixture thickens.
Add ½ pound of butter and continue cooking until it reaches the crack stage.
Shape and pull
Pour the mixture onto a greased marble surface, folding in the edges as it cools.
Add 1 teaspoon of oil of lemon and pull the mixture over a hook until it becomes light and spongy.
Form the mixture into 1 or 2 round loaves, similar to bread, and break off pieces as needed.

Cream and lemon barely smell alike, yet cooks put them together in 15,640 recipes: they work on texture and structure more than aroma.
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 sweetness that define the candy.
- Glucose
- Inhibits sugar crystallization, keeping the candy smooth and glossy rather than grainy.
- Cream of tartar
- Acts as an acid that helps prevent sugar crystallization, giving a tender texture.
- Butter
- Adds fat for richness and a softer bite in the finished candy.
The step that matters
Cooking to the crack stage. Sugar syrup must reach the correct temperature to set firm yet not brittle. Under-cooking leaves it sticky, while over-cooking makes it hard and difficult to pull into a light, spongy texture.
