Coffee Buns

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the dough

  1. Rub the butter into the flour.

  2. Add the baking powder, currants, salt, spice, ground rice, coffee essence, and brown sugar.

  3. Mix to a stiff paste with the egg and milk.

Shape and bake

  1. Place the mixture in heaps on a greased baking tin.

  2. Brush with egg if desired.

  3. Bake for 15 to 20 minutes.

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

What each ingredient does

Flour
Provides the structure that holds the buns together as they bake.
Butter
Rubbed into the flour to add richness and a tender, crumbly texture.
Egg
Binds the mixture into a paste and adds richness and colour to the crust.
Baking powder
Releases gas in the oven so the buns rise and lighten.
Brown sugar
Adds sweetness and moisture, and helps the crust brown.
Coffee essence
Gives the buns their coffee flavour.

The step that matters

Mix to a stiff paste. The paste should be stiff, not wet. Too much milk makes the buns spread and lose their shape, while a dry paste bakes up crumbly and uneven.

Swap the currant

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

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