Why it works: Almond and biscuit match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 388 recipes. Both carry nonanal, which smells fat, citrus. The science ↓

Ingredients
Directions
The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the paste
Beat the almond goods and biscuits in a clean mortar until fine.
Pass the mixture through a sieve.
Return the mixture to the mortar and beat in the yolks of eggs to form a moderately stiff paste.
Shape the sandwiches
Roll out the paste into a sheet about 1/8 inch thick.
Spread a thin layer of raspberry jam on the sheet.
Roll out another sheet of the same size and thickness.
Place the sheet on top of the jam.
Cut into pieces about 3 inches long and 1 to 1.5 inches wide.
Ice and bake
Prepare icing with egg whites and loaf sugar.
Spread the icing evenly over the pieces.
Place the biscuits on a tin covered with wafer paper, leaving 1 inch between each.
Bake in a cool oven at 300°F (150°C) with the door open until the icing is a pale delicate brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Almond goods
- Provide the main almond flavour and the body of the paste.
- Common biscuits or stale sponge cakes
- Add dry crumb that helps bind the paste and gives it structure.
- Yolks of eggs
- Bind the crumbs into a stiff paste that holds its shape when rolled.
- Raspberry jam
- Adds fruit sweetness and moisture between the two sheets.
- Egg whites and loaf sugar icing
- Forms a sweet crust that sets and browns lightly in the oven.
The step that matters
Bake in a cool oven with the door open. A low oven with the door open dries the surface slowly and sets the icing without scorching it, so the biscuits brown only pale and delicate rather than darkening or drying out in the centre.

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