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.

Prepare the dough

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

  2. Mix the flour, butter, sugar, baking powder, and candied peel in a bowl.

  3. Beat the eggs, reserving a small amount for glazing the buns.

  4. Add the beaten eggs and enough milk to form a stiff paste.

Shape and bake

  1. Divide the mixture into 15 pieces and shape them into balls.

  2. Brush the tops with the reserved egg and sprinkle with sugar.

  3. Bake for 20 minutes until golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 buns together as they bake.
Butter
Adds richness and tenderness to the crumb.
Eggs
Bind the dough and add structure and richness.
Baking powder
Releases gas in the heat so the buns rise and become light.
Milk
Hydrates the flour to form a stiff paste that holds its shape.
Sugar
Adds sweetness and helps the tops brown during baking.

The step that matters

Add the milk gradually to form a stiff paste. Too much liquid makes the dough slack so the balls spread instead of holding their shape, while too little leaves the flour dry and the buns dense.

Swap the lemon
