Oranges Preserved

Ingredients

Directions

Prepare the oranges

  1. Grate the rinds of the oranges slightly and score them with a knife, cutting into shapes without cutting deep.

  2. Soak the oranges in cold water for three days, changing the water two or three times daily.

  3. Tie the oranges in a bag and boil them in water until a pin can easily penetrate their skins.

Make the syrup and cook

  1. For the syrup, combine 1.5 pounds of sugar with ½ pint of water for each pound of oranges in a pot.

  2. Boil the sugar and water mixture for 1-2 minutes, then strain it through muslin.

  3. Add the oranges to the syrup and boil until the syrup thickens and turns a nice yellow color, turning the oranges to ensure even cooking.

    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
Provide the fruit and rind that are preserved and candied in the syrup.
White sugar
Preserves the fruit and thickens the syrup as it cooks down, adding sweetness.
Water
Dissolves the sugar into syrup and carries the sugar into the fruit during cooking.

The step that matters

Boiling the oranges in syrup until thickened and yellow. Sugar must slowly penetrate the peel and the syrup must reduce to the right thickness. Turning the oranges keeps cooking even so no part is under-preserved or scorched.
