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

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

Make the dough

  1. In a bowl, mix the flour, butter, sugar, eggs, essence of lemon, currants, and enough milk to form a smooth dough.

Shape and bake

  1. Roll out the dough and cut it into shapes using a fluted cutter.

  2. Place the biscuits on a baking tray and bake in the hot oven 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 of the biscuits as it binds with the liquid.
Butter
Adds fat that tenderises the crumb and gives a rich flavour.
Sugar
Adds sweetness and helps the biscuits brown in the oven.
Eggs
Bind the dough and add richness and structure to the biscuits.
Currants
Add pockets of sweetness and chew throughout the biscuits.

The step that matters

Bake until golden. Baking in a hot oven sets the dough quickly and drives browning. Removing the biscuits too early leaves them pale and soft, while leaving them too long dries them out and makes them hard.

Swap the currant
