Why it works: Chocolate and walnut are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 1,548 recipes. Both carry 3-ethyl-2,5-dimethylpyrazine, which smells roasted, nutty. The science ↓
Chocolate Wafers
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream the shortening and sugar together.
Add the eggs, grated chocolate, and sifted flour mixed with baking powder, then mix until well combined.
Shape and bake
Roll the dough very thin.
Bake in a moderate oven at 350°F (175°C) until done.

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.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Flour
- Provides the structure that holds the wafers together as they bake.
- Eggs
- Bind the dough and add moisture and structure to the wafers.
- Shortening
- Adds fat that tenderizes the dough and gives a short, crisp bite.
- Sugar
- Sweetens the dough and helps it brown while baking.
- Baking powder
- Releases gas in the oven to lift and lighten the dough.
- Grated chocolate
- Adds chocolate flavor and darkens the color of the wafers.
The step that matters
Roll the dough very thin. Thin dough dries out and crisps in the oven, while thick dough stays soft and cakey in the middle. Even thickness also helps the wafers bake evenly.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, flour, egg, chocolate):
- Almondfits better
- Hazelnutfits better
- Chestnutfits better
- Walnutthe original
Fit is the average pairing score against sugar, flour, egg, chocolate. Candidates are from the same food group and used in at least 100 recipes.
