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 recrystallizing, so the brittle stays smooth and crisp rather than grainy.
Sugar
Provides the sweetness and forms the hard, glassy structure of the brittle as it cooks.
Black walnut meats
Add nutty flavor and crunchy texture throughout the brittle.

The step that matters

Cooking to 290°F (143°C) after adding the walnuts. Sugar syrup must reach the hard-crack range to set crisp when cooled. Stopping early leaves the brittle soft or sticky, while overcooking can scorch the sugar and give a bitter taste.

Swap the walnut

How well each one fits the dish's main ingredients (sugar, meat):

  1. Almondfits about as well
  2. Chestnutfits about as well
  3. Pecansfits about as well
  4. Walnutthe original

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