Geneva Wafers

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the batter

  1. Preheat the oven to 300°F (150°C).

  2. Whisk the eggs in a basin until well combined.

  3. Stir in the softened butter until creamy.

  4. Gradually add the flour and powdered sugar, mixing well.

  5. Butter a baking sheet and drop a teaspoonful of the mixture onto it, leaving space between each.

Bake and shape

  1. Bake until half done, then roll each wafer up like dumplings, using a small wedge of bread or piece of wood to keep their shape.

  2. Return to the oven until crisp.

Fill and serve

  1. Before serving, remove the bread, fill the widest end with a spoonful of preserves, and top with whipped cream.

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

What each ingredient does

Eggs
Provide structure and moisture, binding the batter and helping the wafers set.
Butter
Adds fat and richness, giving the wafers a tender texture and flavour.
Flour
Forms the structure that holds the wafers together as they bake.
Powdered sugar
Sweetens the wafers and helps them brown and crisp in the oven.

The step that matters

Baking until half done before rolling. The wafers must be partly set but still pliable. If they are underbaked they tear when rolled, and if overbaked they crack and cannot be shaped, so timing controls both shape and crispness.
