Why it works: Orange and sugar are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 19,212 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
To Preserve Oranges Whole
Ingredients
Directions
Prepare the oranges
Grate the rinds of the oranges slightly and score them with a knife.
Soak the oranges in cold water for three days, changing the water two or three times a day.
Tie the oranges in a bag and boil them until a pin can easily penetrate their skins.
Make the syrup and cook
For every pound of oranges, combine 1½ pounds of sugar with ½ pint of water in a pot and bring to a boil.
Strain the syrup through muslin and place the oranges in the syrup.
Boil the oranges in the syrup until it jellies and turns a nice yellow color.
Ensure the syrup coats the oranges well, but it does not need to cover them completely.

Shared aroma: beta-damascenone (apple, rose).
Orange and sugar barely smell alike, yet cooks put them together in 19,212 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Oranges
- The fruit is the main product, and boiling softens its rind and skins.
- White sugar
- Sweetens the fruit and, as the syrup concentrates, thickens it so it jellies.
The step that matters
Boil the oranges in the syrup until it jellies. The syrup must concentrate enough for sugar to set into a jelly as it cools. Stopping too early leaves it runny, while boiling too long can darken the syrup and turn the sugar bitter.
