Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Chocolate Taffy
Ingredients
Directions
Make the taffy base
In a kettle, combine glucose, sugar, and water. Stir until dissolved.
Cook the mixture until it reaches 258°F (126°C).
Remove from heat and add the chocolate, mixing well.
Return to heat and bring to a boil again, then pour onto a greased slab.
Pull and shape
After a few minutes, fold in the edges and knead until partly cool.
Place on a hook and pull while adding vanilla flavor.
Once well pulled, form into strips and cut into 5-cent bars.

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
- Glucose
- Keeps the sugar from crystallising, giving the taffy a smooth, chewy texture.
- Sugar
- Provides sweetness and, once cooked to temperature, the firm body of the taffy.
- Bitter chocolate
- Adds deep chocolate flavour and dark colour to the taffy.
The step that matters
Cooking to 258°F (126°C). The syrup must reach the target temperature to set the right balance of moisture and sugar concentration. Too little cooking leaves the taffy sticky and soft; too much makes it hard and brittle.
