Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Butter Dainties
Ingredients
Directions
The book gives no oven temperature. The 275°F (135°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the mixture
In a large pot, combine glucose, brown sugar, granulated sugar, butter, and flour.
Cook the mixture to 275°F (135°C).
Add salt and oil, along with the juice of one lemon.
Cool and shape
Pour the mixture onto a slab and let it cool.
Once cool, run it through a rolling pin to shape.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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 mixture from crystallizing, giving a smooth, glassy texture.
- Brown sugar
- Adds sweetness and moisture, along with a deeper caramel flavor.
- Granulated sugar
- Adds sweetness and helps the mixture set firm as it cools.
- Butter
- Adds fat for richness and a buttery flavor.
- Flour
- Provides structure so the cooked mixture holds its shape.
The step that matters
Cook the mixture to 275°F (135°C). Sugar mixtures set according to their final temperature. Undercooking leaves the candy soft and sticky, while overcooking makes it hard and brittle or darkens it too much.
