Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. In a basin, combine the flour and butter, rubbing the butter into the flour.

  2. Cream the yeast with the sugar and strain it into the center of the flour.

  3. Add the warm milk and drop in the eggs, then beat the mixture until air bubbles form.

  4. Cover with a cloth and let it rise in a warm place for 2 hours.

Shape and bake

  1. Once risen, mix in the sugar, candied peel, and sultanas.

  2. Form the mixture into small round buns and place sugar pieces on top.

  3. Let the buns prove in a warm place for 20 minutes.

  4. Bake in a hot oven at 400°F (200°C) for 10 minutes.

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

What each ingredient does

Flour
Forms the structure that holds the dough and buns together as they rise.
Butter
Adds fat for a tender crumb and rich flavor.
German yeast
Produces gas that makes the dough rise and become airy.
Eggs
Add structure, richness, and moisture to the dough.
Sultanas
Add sweetness and chewy fruit pieces throughout the buns.

The step that matters

Let the dough rise fully before adding the fruit. Yeast needs time in a warm place to produce gas and expand the dough. Under-proofed dough stays dense, while the rise gives the buns their light, airy texture.
