Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Molasses Chips
Ingredients
Directions
Make the candy base
In a kettle, combine 8 lbs sugar, 2 lbs glucose, and 3 pints water.
Cook the mixture to 300°F (150°C).
Add ½ lb butter and 1 pint molasses, then boil well.
Remove from heat and pour onto a greased slab.
Pull and shape
Knead the mixture with gloves on and pull it while adding a few drops of lemon.
When well pulled, twist out the air and place it on a table before a table furnace.
Flatten it out and form it into a ham shape.
Pull out strips about 1 inch wide and as thin as cardboard.
Mark in 1½ inch lengths and break apart.
Dip in vanilla coating.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Sugar
- Forms the main structure of the candy as it cooks and sets.
- Glucose
- Inhibits crystallization, keeping the candy smooth and pliable rather than grainy.
- Molasses
- Adds dark color, deep flavor, and moisture to the candy.
- Butter
- Adds fat that softens the texture and gives a richer mouthfeel.
The step that matters
Cooking to 300°F (150°C). This is the hard-crack stage, where the sugar concentration is high enough for the candy to set firm and brittle. Undercooking leaves it sticky, while overcooking can scorch it and give a bitter taste.
Swap the lemon

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