Why it works: Vanilla and almond match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,961 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Biscuit Glace or Tortoni
Ingredients
Directions
Make the syrup and custard base
Boil sugar and water until dissolved to make a thick syrup.
Beat the egg yolks in a bowl.
When the syrup is cool, add it to the beaten egg yolks with the cream.
Cook the mixture over a double boiler until it coats the back of a spoon like custard.
Chill and whip
Place the mixture in a dish of ice water and whip until cold.
Fold in the whipped heavy cream and flavor with vanilla or maraschino.
Pack and freeze
Transfer the mixture to paper boxes and sprinkle the top with chopped almonds or crushed macaroons.
Stack the boxes in a tin pail, placing paper between each layer.
Pack the pail in ice and salt for four hours.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Egg yolks
- Thicken the custard base when gently cooked and provide richness and a smooth texture.
- Heavy cream
- Whipped and folded in to add lightness and a creamy, airy texture.
- Sugar
- Sweetens the base and, dissolved into syrup, helps keep the frozen texture smooth.
The step that matters
Cook the mixture over a double boiler until it coats the back of a spoon like custard.. Egg yolks thicken with gentle heat, and overheating can scramble them into lumps. Gentle, indirect heat in a double boiler keeps the custard smooth.
Swap the almond
How well each one fits the dish's main ingredients (sugar, egg, cream, vanilla):
- Almondthe original
- Chestnutfits about as well
- Hazelnutfits about as well
- Macadamia nutfits less well
Fit is the average pairing score against sugar, egg, cream, vanilla. Candidates are from the same food group and used in at least 100 recipes.
