Route Biscuits

Oven, in the book's wordsA moderate oven

Ingredients

Directions

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

Make the dough

  1. In a large bowl, combine flour, butter, powdered sugar, ground almonds, and baking soda.

  2. Add enough milk to form a dough.

Shape and bake

  1. Roll out the dough and cut into fancy shapes.

  2. Bake in a moderate oven at 350°F (175°C) until pale brown.

  3. Move biscuits to the front of the oven to dry and crisp.

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

What each ingredient does

All-purpose flour
Provides the main structure that holds the dough together as it bakes.
Unsalted butter
Adds fat that gives the biscuits a tender, crumbly texture.
Powdered sugar
Sweetens the biscuits and dissolves finely into the dough for a delicate crumb.
Ground bitter almonds
Adds nutty aroma and flavor to the biscuits.
Baking soda
Helps the biscuits brown and gives a light, slightly open texture.

The step that matters

Move biscuits to the front of the oven to dry and crisp. Once they are pale brown, the biscuits can darken quickly. Moving them to a cooler spot dries the surface gradually, so they crisp without over-browning.
