Breakfast Rolls

Oven, in the book's wordsA hot oven

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.

Prepare

Preheat the oven to 400°F (200°C).

Make the dough

In a bowl, mix the flour, butter, sugar, and salt.
Add sweet milk gradually until a dough forms.
Roll out the dough and cut it into strips.
Form the strips into rolls and place them on a baking sheet.
Brush the tops with egg yolk if using.

Bake

Bake for 10 minutes until golden.

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

What each ingredient does

All-purpose flour: Forms the structure of the dough as its proteins bond with the liquid.
Butter: Adds fat that tenderizes the crumb and helps the rolls brown.
Sweet milk: Hydrates the flour so the dough comes together and bakes into a soft texture.
Egg yolk: Adds richness and promotes even browning on the brushed tops.
