Another Way to Preserve Oranges Whole

Ingredients

Directions

Prepare the oranges

  1. Cut the rind of the oranges into narrow strips, being careful not to cut too deep.

  2. Soak the oranges in cold water for 2 days, changing the water twice daily.

  3. Boil the oranges in plenty of water for about 2 hours, changing the water several times until tender.

Make the syrup and preserve

  1. To make the syrup, boil the sugar with water for a few minutes and skim before adding the oranges.

  2. Drain the water and boil the oranges in the syrup for 30 minutes.

  3. Let the oranges stand for a week, then boil again for 30 minutes or less if the syrup is a good color and not too watery.

What each ingredient does

Oranges
Thick rind and pith are softened by soaking and boiling, so the peel becomes tender to eat.
Loaf sugar
Forms a thick syrup that preserves the oranges and gives them their sweetness.

The step that matters

Boiling the oranges until tender in plenty of water. Thick rind is slow to soften, and sugar in the syrup will not penetrate properly if the peel is still firm. Changing the water removes bitterness and loosens the rind, so the oranges must be checked for tenderness before moving on to the syrup.
