Quince Preserves
Ingredients
Directions
Prepare
Ensure quinces are thoroughly ripe. If green, let them ripen until yellow.
Pare and quarter the quinces, saving the waste for jelly juice.
Make the preserves
Cook the quinces in water until soft, but not long enough to peel off.
Add the sugar and cook slowly; the longer they cook, the better the color.
Cook the quinces to 220°F (104°C).
Process
Process for 35 minutes at 180°F (82°C).

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Quinces
- Provide the fruit body, firm texture, and natural pectin that helps the preserves set.
- Granulated sugar
- Adds sweetness, draws water out of the fruit, and helps the cooked quinces darken to a richer color.
The step that matters
Cook the quinces in water until soft, but not long enough to peel off.. Quince flesh softens gradually, and overcooking breaks down its structure so the pieces fall apart instead of holding their shape in the preserves.
