Bath Buns

Oven, in the book's wordsA quick oven

Ingredients

Directions

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

Make the dough

  1. Mix and sift the flour, baking powder, salt, sugar, and cinnamon.

  2. Add the grated lemon rind and chopped citron.

  3. Rub in the butter until well combined.

  4. Beat the egg yolks and mix with the milk, then combine with the dry ingredients to form a soft dough, adding more milk if needed.

Shape and bake

  1. Mold the dough into round buns and place them 1 inch apart on greased pans.

  2. Brush the buns with milk and sprinkle with chopped citron.

  3. Bake in a 400°F (200°C) oven until golden.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Butter
Rubbed into the flour, it coats flour particles and gives the buns a tender, crumbly texture.
Egg yolks
Add richness and fat, and help bind the dough while adding color and tenderness.
Baking powder
Releases gas when heated, helping the buns rise and become light.
Milk
Hydrates the flour to form the dough and adds moisture for a soft crumb.
Sugar
Adds sweetness and helps the buns brown in the oven.
Flour
Provides the structure that holds the buns together as they bake.
