Ingredients

Directions

The book says “a cool oven”. The 300°F in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Grind the almonds with the grated lemon to form a stiff paste.

  2. Add cochineal to color the mixture red.

Bake

  1. Lay small lumps of the paste on wafer paper.

  2. Bake in a very cool oven (300°F / 150°C) until set.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 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

Almonds
Form the main body of the paste, giving the biscuits their structure and nutty flavor.
Grated lemon
Adds aromatic citrus flavor and its oils scent the paste.
Sugar
Adds sweetness to balance the almonds and lemon.

The step that matters

Bake in a very cool oven until set. A very low oven sets the paste slowly without browning it. Too hot an oven can scorch the surface or spread the lumps before they firm up.

Swap the lemon
