Orange Preserves

Ingredients

Directions

Prepare the oranges

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

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

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

Make the syrup

  1. In a separate pot, combine the sugar with ½ pint of water for each pound of sugar and boil for 1–2 minutes.

  2. Strain the syrup through muslin.

Cook the preserve

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

  2. Test the syrup by cooling a small amount.

  3. Check that the syrup is not too stiff.

  4. Ensure the syrup does not cover the oranges completely.

  5. Turn the oranges to ensure even cooking.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    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 bulk of the preserve and the peel and pulp that set and flavour it.
White sugar
Sweetens the preserve and, once boiled with water, helps the syrup thicken and set.

The step that matters

Testing the syrup for set. Sugar and pectin only gel within a narrow concentration and temperature range. Cooling a small sample shows whether the syrup will set, so the cook can stop before it turns stiff or stays runny.
