Savoy Biscuit

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.

Make the batter

  1. Combine egg yolks, sugar, and lemon zest in a round-bottomed bowl.

  2. Beat until stiff, light batter.

  3. Whip egg whites until very firm.

  4. Fold the egg whites into the batter.

  5. Stir in flour carefully.

Shape and bake

  1. Pipe the mixture into strips about 3 inches long onto parchment paper.

  2. Sift sugar over the biscuits and shake off the excess.

  3. Bake at 400°F (200°C) until done.

Finish

  1. Once baked, cut them apart and join two biscuits together.

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

What each ingredient does

Eggs
Whipped whites and yolks provide the airy structure that lets the batter rise and hold its shape.
Fine flour
Provides the starch and gluten-free-to-set framework that holds the light batter together as it bakes.
Sugar
Sweetens the biscuits and helps stabilise the whipped egg foam while adding a crisp sugared surface.

The step that matters

Folding the egg whites into the batter. Whites hold air only when whipped firm; overmixing or deflating them while folding makes the batter heavy and the biscuits flat and dense.

Swap the lemon

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

  1. Raisinfits better

  3. Lemonthe original
  4. Figfits about as well

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