Why it works: Sugar and quince are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 1,444 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓

Ingredients
Directions
Prepare the quinces
Pare the quinces and place them in a preserving pan, covering them with cold water.
Press down the quinces with a plate to gauge the water level.
Remove the quinces and measure the water.
Cook the quinces
Add the sugar to the measured water and bring to a rapid boil for 5 minutes.
Add the quinces to the boiling syrup; it should not cover them initially.
Boil the quinces until they are soft enough to pierce easily with a knitting needle, about 1.5 hours.
Carefully remove the quinces and place them on dishes to cool.
Finish the syrup
Strain the syrup through a jelly bag or new flannel to remove any bits.
Return the syrup to the pan and boil until it jellies when dropped on a plate.
Add the quinces back into the syrup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Quinces
- Provide the fruit itself, which softens during long boiling and turns tender and fragrant.
- White sugar
- Sweetens the fruit and, when boiled down, thickens the syrup so it sets to a jelly.
- Water
- Forms the syrup base that dissolves the sugar and carries heat evenly around the fruit.
The step that matters
Boiling the syrup until it jellies. Sugar syrup sets as water evaporates and the sugar concentration rises. Testing by dropping syrup on a cold plate shows when enough water has boiled off; stopping too early leaves a runny preserve.
