Why it works: Cinnamon and vanilla match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,287 recipes. Both carry 4-methoxybenzaldehyde, which smells sweet, anise. The science ↓
Chocolate Filberts
Ingredients
Directions
The book says “a very moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the nuts
Crack the nuts.
Place the nuts in a 350°F (175°C) oven to dry for 30 minutes.
Remove the nuts from the oven.
Rub off the skins from the nuts.
Make the chocolate paste
Grate the chocolate finely.
Mix the grated chocolate with sugar, cinnamon, and vanilla.
Make a thick paste with the chocolate using enough egg whites.
Coat and bake
Place the nuts on a flat dish.
Pour the chocolate paste over the nuts.
Roll the nuts with a small wooden spoon until fully coated.
Dust a baking tin with flour.
Space the coated nuts apart on the tin.
Bake slowly until the chocolate hardens.
If the nuts stick together, separate them when cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Filberts (hazelnuts)
- Form the main body of the confection, providing crunch and nutty flavour.
- Chocolate
- Forms the coating that hardens around the nuts, giving sweetness and rich flavour.
- Egg whites
- Bind the grated chocolate and sugar into a paste that clings to the nuts.
- Sugar
- Sweetens the chocolate coating and helps it set firm as it cools.
The step that matters
Bake slowly until the chocolate hardens. Chocolate that is baked too hot can scorch or separate, while slow heat lets the coating dry and set evenly without burning.
