Why it works: Pineapple and sugar are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 4,841 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Pineapple Preserves
Ingredients
Directions
Prepare the fruit
Cut 1 to 2 inches from the stem of the pineapple.
Place the pineapple in a pot of water (preferably copper) and boil for 5 hours or more.
Test the fruit by running a straw through it; do not let it get too soft.
Once ready, peel the pineapple, removing the eyes, and slice it into thick slices.
Cut out the core and weigh the fruit.
Macerate and cook
Layer the fruit and sugar alternately in a stone or earthen jar, covering the top with sugar, and let it sit overnight.
In the morning, drain off the syrup, scraping every piece of fruit with a silver knife.
Bring the syrup to a boil and skim off any foam.
Carefully add the fruit to the boiling syrup and cook for 10 minutes.
Jar and finish
Remove the fruit and place it in jars.
Continue to cook the syrup until it thickens, then pour it over the fruit, ensuring it is well covered.

What each ingredient does
- Pineapple
- Forms the main body of the preserves and supplies the fruit texture and flavor.
- Granulated sugar
- Draws water out of the fruit and thickens the syrup, while acting as a preservative.
The step that matters
Boiling the pineapple until tender but not soft. Boiling softens the fruit so the sugar can penetrate, but over-softened fruit breaks apart and turns mushy in the preserves. The straw test checks the fruit before it goes further.
