Why it works: Quince and lemon match in chemistry and in kitchens. They rank in the top 11% of all ingredient pairs, and cooks put them together in 336 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Quince Preserve
Ingredients
Directions
Pare and core the quinces, then cut them into halves or quarters.
Soak the quinces in cold water with a little lemon juice to prevent discoloration.
Cook the quinces in boiling water until tender enough to pierce with a fork.
Drain the water and add the peel, cores, and pips back to the water.
Boil the mixture slowly for 30 minutes, then strain through a double layer of cheesecloth.
For every cup of liquid, add one cup of sugar.
If clarifying, add the egg white and shell, then follow directions for clarifying syrup.
Bring the syrup to a boil, add the quinces, and cook gently until the fruit is preserved.
Fill dry, sterilized jars with the preserve and screw the lids down tightly.
