Lemon Snaps

Oven, in the book's wordsA moderately quick oven

Ingredients

Directions

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

Prepare the dough

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

  2. Cream the butter and sugar together until light and fluffy.

  3. Add the water, baking powder, lemon rind, and lemon juice; mix well.

  4. Gradually add flour until the dough is firm enough to roll out.

  5. Roll out the dough and cut into desired shapes.

Bake and finish

  1. Place the cutouts on a baking sheet, brush with egg white, and sprinkle with sugar.

  2. Bake in the preheated oven until lightly golden.

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

What each ingredient does

Butter
Creaming with sugar traps air and adds richness and tenderness to the snaps.
Sugar
Sweetens the snaps and, creamed with butter, helps give a light, crisp texture.
Baking powder
Releases gas in the oven so the snaps rise slightly and bake up lighter.
Lemon rind and juice
Provides bright lemon aroma and acidity that cuts the sweetness.
Flour
Forms the structure of the dough so it can be rolled and cut into shapes.
Egg white
Brushed on top to help the sugar stick and add a glossy, browned finish.

The step that matters

Adding flour gradually. Adding flour in small amounts lets you stop when the dough is firm enough to roll. Too much flour makes the snaps dry and tough, while too little leaves the dough sticky and hard to cut.
