Preserved Oranges

Ingredients

Directions

Prepare the oranges

  1. Grate the oranges lightly and score them with a knife, but do not cut deep.

  2. Soak the oranges in cold water for 3 days, changing the water 2-3 times daily.

  3. Tie the oranges in a cloth and boil them until a pin can easily penetrate the skin.

Make the syrup

  1. For the syrup, combine 1 pint of water for each pound of sugar in a pot and bring to a boil for 1-2 minutes.

  2. Strain the syrup through muslin.

Preserve and check

  1. Add the oranges until the syrup jellies and turns yellow.

  2. Check the syrup by cooling a small amount; it should not be too stiff.

  3. Turn the oranges in the syrup to ensure even coating.

    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 bitter peel that are candied and preserved in the syrup.
White sugar
Forms the thick syrup that preserves the fruit and sets it into a jelly-like coating.
Water
Dissolves the sugar into syrup and carries it into the fruit as it cooks.

The step that matters

Checking the syrup consistency. Sugar syrup thickens and sets as it cools, so if it is too stiff the oranges may end up hard and sugary, and if too thin it will not preserve them well.
