Ingredients

Directions

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

Make the dough

  1. Mix flour, melted butter, baking soda, beaten egg yolk, and salt in a bowl.

  2. Knead the dough for 10 minutes, starting gently to avoid wasting liquids.

  3. Roll out the dough to ½ inch thick using a floured rolling pin.

Shape and rise

  1. Cut into round cakes and place them closely together in a greased pan.

  2. Prick each cake with a fork.

  3. Let them rise for 30 minutes, covered with a cloth.

Bake and serve

  1. Bake in a preheated oven at 400°F (200°C) for 20 to 25 minutes, turning the pan once.

  2. Remove from the oven.

  3. Break apart the biscuits.

  4. Serve on a plate covered with a clean napkin.

The flavor team

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.

    Shared aroma: decanal (soap, orange peel).

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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 main structure of the dough as its proteins and starch set in the oven.
Melted butter
Adds fat and richness, tenderizing the crumb and helping the biscuits brown.
Baking soda
Reacts with the dough to produce gas that helps the biscuits rise.
Egg yolk
Adds richness and binds the dough together, contributing color and tenderness.

The step that matters

Knead gently at first. Starting slowly keeps the dough from losing liquid and becoming dry or tough. Overworking develops too much gluten, which makes the biscuits dense and chewy.
