Geneva Wafers

Oven, in the book's wordsA moderate oven

Ingredients

Directions

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

Make the batter

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

  2. Beat in each egg separately.

  3. Add a few drops of vanilla and stir in the flour lightly.

  4. Transfer the mixture to a piping bag fitted with a large plain tip.

Pipe and bake

  1. Pipe small portions onto a well-buttered baking sheet, filling each portion to just about a teaspoon.

  2. Spread each portion thinly with a hot, wet palette knife.

  3. Bake in a moderate oven (350°F / 175°C) until set.

  4. Carefully remove them with a palette knife and wrap around buttered cornet tins.

  5. Place one tin inside the other to maintain shape, then return to the oven and bake until lightly browned, turning frequently.

Fill and serve

  1. Once cool, remove the moulds and fill with whipped sweetened cream and a little jam.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Butter
Creamed with sugar to trap air and give the wafers a rich, tender texture.
Eggs
Add structure and moisture, helping the batter set as it bakes.
Fine flour
Provides the structure that holds the thin wafers together once baked.
Castor sugar
Sweetens the batter and helps create a light, creamed texture with the butter.
Apricot jam
Adds sweetness and fruity flavour to the filling.

The step that matters

Spreading the thin portions. Each portion must be spread very thin so the wafer bakes crisp and evenly; thick portions stay soft and won't hold their shape when rolled around the tins.

Swap the apricot

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

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