Why it works: Walnut and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 5,873 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Gum Drop Cookies
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Mix and bake
Combine all ingredients in a mixing bowl; do not chop the gum drops.
Drop spoonfuls of the mixture onto a cookie sheet.
Bake until golden, then cut into squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and moisture to the cookies.
- Brown sugar
- Adds sweetness, moisture and a caramel-like depth to the cookies.
- Pastry flour
- Provides the starch and gluten structure that holds the cookies together.
- Gum drops
- Melt slightly in the oven, adding chewy texture and sweetness.
- Walnut meats
- Add crunch and a nutty flavour that contrasts with the chewy texture.
The step that matters
Combine all ingredients without chopping the gum drops. Leaving the gum drops whole keeps pockets of chewy sweetness intact; chopping them releases more sugar and colour into the batter, which can make the cookies stickier and more uneven as they bake.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, meat, flour, egg):
- Almondfits better
- Chestnutfits about as well
- Walnutthe original
- Pistachiofits about as well
Fit is the average pairing score against sugar, meat, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
