Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Demerara sugar
Provides the main sweetness and the caramel flavour as it cooks down.
Butter
Adds fat for richness and a smooth, tender bite.
Milk
Adds moisture and milk solids that give the toffee a creamier, softer texture.
Baking soda
Raises the pH, which deepens browning and lightens the texture.
Ginger
Adds a warm, spicy aroma and flavour.

The step that matters

Boiling the mixture. As the mixture boils, water evaporates and the sugar concentrates, so it can scorch or burn on the bottom of the pot. Stirring frequently spreads the heat evenly and keeps the sugar from sticking. Adding baking soda makes the mixture foam up sharply, so the pot needs room.

Swap the ginger

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Gingerthe original
  4. Clovefits about as well

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