Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
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
Preheat the oven to 300°F (150°C).
Whisk the eggs in a basin until well combined.
Stir in the softened butter until creamy.
Gradually add the flour and powdered sugar, mixing well.
Butter a baking sheet and drop a teaspoonful of the mixture onto it, leaving space between each.
Bake and shape
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.
Return to the oven until crisp.
Fill and serve
Before serving, remove the bread, fill the widest end with a spoonful of preserves, and top with whipped cream.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
