Cornish Biscuits

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the dough

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

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

  3. Add butter and mix until crumbly.

  4. Stir in beaten eggs, caraway seeds, raisins, and currants.

  5. Add milk gradually until the dough is soft enough to handle.

Shape and bake

  1. Pat the dough out on a floured surface into a sheet.

  2. Cut with a small biscuit cutter.

  3. Bake in the preheated oven until almost done.

  4. Remove from the oven and butter the tops.

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 that holds the biscuits together as they bake.
Baking powder
Releases gas in the oven, helping the biscuits rise and become light.
Butter
Coats flour particles when rubbed in, giving a crumbly, tender texture.
Eggs
Bind the dough and add richness and structure.
Sugar
Adds sweetness and helps the tops brown in the oven.
Raisins
Add concentrated sweetness and chewy moisture throughout the biscuits.

The step that matters

Adding the milk gradually. Flour hydrates as it is mixed, so adding milk a little at a time lets you stop once the dough is soft but not sticky. Too much liquid makes the biscuits dense and hard to cut cleanly.

Swap the currant

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

  1. Vanillafits better
  2. Figfits better
  3. Lemonfits better
  4. Currantthe original

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