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

What each ingredient does

Bread dough
Provides the soft, airy crumb structure that holds the rolls together.
Butter
Adds richness and tenderness, and the melted coating helps the rolls brown.
White sugar
Sweetens the rolls and helps them brown in the oven.
Dried currants
Add concentrated sweetness and chewy bits of fruit throughout the rolls.

The step that matters

Bake until golden. Baking only until golden keeps the rolls from drying out, while stopping too early leaves the dough pale and underbaked inside. Sugar and butter brown through the Maillard reaction and caramelization, so color is a useful cue.

Swap the currant

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

  1. Raisinfits better
  2. Vanillafits better
  3. Figfits better
  4. Currantthe original

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