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, Bottled
Ingredients
Directions
Prepare the fruit
Ensure the pineapples are perfectly sound and ripe.
Peel and remove any specks.
Cut the fruit into 1/2-inch thick slices and divide the slices into halves.
Place the pineapple halves into dry wide-mouthed bottles.
Wrap a wisp of hay around each bottle.
Make the syrup
Dissolve the sugar in water to make the syrup.
Stir in the egg white.
Heat the syrup for 2-3 minutes and allow it to boil.
Skim the syrup carefully.
Add a spoonful of cold water to help the scum rise.
Strain the syrup through a napkin before using.
Bottle and process
Cover the pineapple halves with syrup.
Arrange the bottles side by side in a boiler, with cold water up to their necks.
Bring the water to a boil.
Let it boil gently for 20 minutes.
Remove the pan from heat.
Cork the bottles.
Let the bottles cool completely.
Wax the corks.
Store the bottles in a cool cellar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe pineapples
- Provide the fruit, whose flesh softens and becomes sweet during gentle cooking in syrup.
- Loaf sugar
- Makes the syrup that sweetens the fruit and helps preserve it.
- Egg white
- Its proteins coagulate when heated, trapping impurities so they rise as scum to be skimmed off.
The step that matters
Skim the syrup carefully. Egg white clarifies the syrup as it heats: impurities bind to the coagulating protein and rise as scum. Skimming thoroughly leaves a clear syrup and a cleaner-looking preserved fruit.
