Why it works: Butter and cream 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 ↓
Nut-chewing Taffy
Ingredients
Directions
Cook the base
Combine glucose, sugar, and water in a kettle.
Cook over heat until it reaches 275°F (135°C).
Remove from heat and stir in the butter until well mixed.
Pour onto a greased slab.
Pull the taffy
Once cool enough to handle, place on a hook and pull while gradually adding the cream and vanilla flavor.
Dust your hands with starch as needed to prevent stickiness.
Knead in the walnut pieces after pulling.
Shape and wrap
Spread out on the slab.
Cut into squares.
Wrap in wax paper.
Alternatively, spin out and cut into kisses, then wrap.

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 crystallizing too coarsely, giving a smooth, chewy texture.
- Sugar
- Provides sweetness and the structure that sets as the candy cools.
- Butter
- Adds fat for richness and a tender, softer bite.
- Cream
- Adds fat and milk solids that make the taffy lighter and creamier in colour and texture.
- Walnut pieces
- Add crunch and a nutty flavour that contrasts with the chewy candy.
The step that matters
Pulling the candy once it is cool enough to handle. Pulling while the sugar mass is warm but firm incorporates air and encourages fine crystals, which makes the taffy opaque and light. Pulling too hot makes it sticky and soft, and waiting too long makes it too stiff to stretch.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, butter, cream, vanilla):
- Almondfits better
- Chestnutfits better
- Hazelnutfits better
- Walnutthe original
Fit is the average pairing score against sugar, butter, cream, vanilla. Candidates are from the same food group and used in at least 100 recipes.
