Why it works: Almond and lemon match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 5,655 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Sweet Macaroons
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare the almonds
Blanch the almonds and soak them in cold water for a few minutes.
Dry the almonds in a napkin and let them sit for 24 hours.
Pound the almonds in small batches, adding egg whites until a fine paste forms.
Make the paste
Pound and sift the sugar, then mix it with the almond paste and lemon rind.
Add enough egg whites to moisten the paste until it is thin but not runny.
Bake
Spoon the mixture onto sheets of white paper, spacing them at least 1 inch apart.
Bake in a moderate oven (350°F / 175°C) for 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet almonds
- Form the base paste, providing the main structure and nutty flavor of the macaroons.
- Lump sugar
- Adds sweetness and, once dissolved in the moist paste, helps set a crisp, chewy exterior.
- Egg whites
- Bind the paste and add moisture so it can be spooned and holds its shape.
- Lemon rind
- Adds aromatic citrus flavor to the almond and sugar paste.
The step that matters
Adding egg whites to the paste. Too little egg white leaves the paste dry and crumbly, while too much makes it runny and it spreads in the oven. Aim for a thin but not runny consistency, since the moisture controls how the macaroons spread and set.
