Spanish Buns

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Preheat the oven to 350°F (175°C).

  2. Beat the butter and sugar together until creamy.

  3. Beat the eggs separately and then add them to the butter mixture.

  4. Stir in the milk and cinnamon.

  5. Gradually add the flour and mix until smooth.

Bake and ice

  1. Pour the batter into a shallow pan and bake until done.

  2. Mix the egg white with a little sugar and ½ teaspoon of cinnamon.

  3. Spread the icing over the top of the baked buns.

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

What each ingredient does

Eggs
Bind the batter and add structure and richness as they set in the oven.
Butter
Adds fat for a tender crumb and rich flavour.
Sugar
Sweetens the batter and helps it brown in the oven.
Flour
Provides the main structure that holds the buns together as they bake.
Milk
Adds moisture to the batter so it bakes softly.

The step that matters

Beat the eggs separately and then add them to the butter mixture. Eggs blended into creamed butter and sugar form a smooth emulsion that traps air, which helps the buns rise lightly. Adding them one at a time or too quickly can cause the batter to curdle.
