To Preserve Oranges in Jelly
Ingredients
Directions
Prepare the oranges
Cut a hole in the stem of each orange, about the size of a sixpence, and scoop out the pulp completely.
Tie each orange in muslin and soak them in spring water for two days, changing the water twice daily.
Boil the oranges in the muslin until tender, adding hot water as needed to keep them covered.
Make the syrup
Weigh the oranges before scooping; for every pound of oranges, use two pounds of sugar and one pint of water.
Boil the sugar and water with the juice from the oranges to create a syrup, skimming it well.
Preserve and finish
Let the syrup cool, then add the oranges and boil for half an hour.
If the oranges are not clear, boil them once a day for two to three days.

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.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Seville oranges
- Provide the fruit and juice, and their peel becomes tender and translucent when boiled.
- Double-refined sugar
- Sweetens the dish and, when boiled, thickens the syrup and helps preserve the fruit.
The step that matters
Boiling the oranges until they are clear. Sugar must slowly penetrate the peel. If the oranges are boiled too briefly or too hard, they stay opaque or tough, so repeated gentle boiling over several days is needed to make them clear.
