To Preserve Oranges
Ingredients
Directions
Prepare
Weigh the oranges.
Grate the oranges lightly.
Score the oranges around the fruit, not too deep.
Soak the oranges in cold water for three days, changing the water at least three times a day.
Cook and preserve
Boil the oranges until tender; test by piercing with a pin.
Make a thick syrup with a little more than 1 pound of sugar for every 1 pound of fruit.
Drop the oranges into the syrup and cook until done.

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
- Supply the fruit and peel that become the preserve, giving its bittersweet flavour and firm texture.
- Sugar
- Sweetens the fruit and, dissolved into a thick syrup, preserves it and gives it body.
The step that matters
Boil until tender before adding sugar. Citrus peel is tough and softens slowly. Testing with a pin confirms the peel is tender, so the syrup can penetrate evenly and the finished preserve does not stay chewy.
