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

What each ingredient does

Wholemeal flour
Provides the main structure once the batter sets in the oven.
Butter
Adds fat for a tender crumb and rich flavour.
Brown sugar
Adds sweetness and moisture, and helps the crust brown.
Eggs
Bind the batter and help give the loaf its set structure.
Currants
Add concentrated fruit sweetness and chewy texture throughout the loaf.
Raisins
Add chewy texture and concentrated sweetness throughout the loaf.

The step that matters

Baking until a skewer comes out clean. The loaf is dense and fruit-filled, so the centre can stay wet while the outside browns. Testing the middle with a skewer confirms the eggs and flour have fully set before cooling.

Swap the currant

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

  4. Currantthe original

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