Orange Rock Cakes

Oven, in the book's wordsA cool oven

Ingredients

Directions

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

Prepare

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

  2. In a bowl, mix flour, sugar, and baking powder.

  3. Rub in the butter.

  4. Grate the rind of the orange and add it to the mixture.

Shape and bake

  1. Add the juice of the whole orange and the beaten egg to form a stiff dough.

  2. Take rough pieces of dough, about the size of a walnut, using two forks.

  3. Place them on a baking sheet, leaving space between each piece.

  4. Bake for 10 to 15 minutes until golden.

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 cakes together as they bake.
Butter
Rubbed into the flour to give the cakes a crumbly, tender texture.
Egg
Binds the dough and adds richness and structure.
Baking powder
Releases gas during baking so the cakes rise and stay light.
Sugar
Adds sweetness and helps the cakes brown as they bake.
Orange
Adds moisture and bright citrus aroma from the juice and rind.

The step that matters

Rubbing in the butter. Working the butter into the flour until it looks like fine crumbs coats the flour particles with fat, limiting gluten formation so the cakes stay short and tender rather than tough.

Swap the orange

How well each one fits the dish's main ingredients (flour, sugar, butter, egg):

  1. Raisinfits better

  3. Figfits better
  4. Orangethe original

Fit is the average pairing score against flour, sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
