Arrowroot Biscuits

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

  1. Cream together the butter and sugar in a basin.

  2. Add the egg yolks and arrowroot, mixing well.

  3. Beat the egg whites with a pinch of salt until stiff.

  4. Gently fold the egg whites into the mixture.

Bake

  1. Drop spoonfuls onto greased baking tins.

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

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

What each ingredient does

Butter
Adds fat and richness, giving the biscuits a tender, short texture.
Sugar
Sweetens the biscuits and helps them turn golden as they bake.
Egg yolks
Add richness and moisture, helping bind the dough together.
Arrowroot
Starch that gives the biscuits a light, delicate, tender crumb.
Egg whites
Whipped to stiff peaks, they trap air that lightens the mixture and helps it rise.

The step that matters

Gently fold the egg whites into the mixture. Whipped egg whites hold air bubbles that lighten the biscuits. Stirring vigorously or overmixing knocks that air out, leaving the biscuits dense and flat.

Swap the arrowroot

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

  1. Sweet potatofits better
  2. Asparagusfits better
  3. Leekfits better
  4. Arrowrootthe original

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