Why it works: Quince and almond share more aroma than cooks usually use. They rank in the top 5% of all ingredient pairs, and cooks put them together in 69 recipes. Both carry 2-nonanone, which smells fruity, floral. The science ↓
Quince Tart
Ingredients
Directions
Make the quince marmalade
Combine 1 pound of sugar and 1 pint of water in a brass pan and boil until it forms a syrup.
Add 1 pound of sliced quinces and boil until it becomes a marmalade, stirring constantly.
Stir in 6 ounces of chopped almonds, 2 ounces of chopped citron, the peel of 2 lemons, and the juice of the lemons; boil briefly.
Bake and finish
Cover a baking plate with wafer paper, pour the mixture over it, and smooth it out.
Once baked, beat the juice of 2 lemons with pounded sugar until it is white like ice; cover the tart with this mixture and let it dry in a cool oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Quinces
- Provide the main fruit body and pectin that thickens the mixture into a marmalade.
- Sugar
- Sweetens the tart and, boiled into syrup, helps set the marmalade as it cooks down.
- Almonds
- Add body and a rich, nutty texture to the marmalade filling.
- Lemon juice
- Adds acidity that brightens the sweet fruit and supports the set of the marmalade.
The step that matters
Boiling the quince marmalade while stirring constantly. Quince is dense and sugar-heavy mixtures scorch easily on the base of a pan. Constant stirring keeps the mass from burning and lets the fruit break down evenly into a spreadable marmalade.
