To Preserve Oranges with Marmalade
Ingredients
Directions
Prepare the oranges
Pare the oranges thinly and cut a hole in the stem end.
Remove all the pulp and soak the oranges in salt and water.
Boil the oranges uncovered for a little over an hour.
Prepare a syrup with 1 pound of sugar and 1 pint of water.
Add the boiled oranges to the syrup.
Boil until the oranges look clear.
Make the marmalade
Remove the pulp's seeds and cut one orange into thin slices.
Add the sliced orange to the pulp and mix with double-refined sugar.
Boil the mixture in a clean pan over low heat until clear and transparent.
Fill and preserve
Once cooled, fill the oranges with the marmalade.
Place the filled oranges back in the syrup.
Let them stand for two months.
Prepare a new syrup with double-refined sugar and water.
Boil the oranges in the new syrup.
Cover with brandy papers and tie them down with a bladder.

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
- Oranges
- Their peel and pulp form the shell and the marmalade filling of the dish.
- Fine loaf sugar
- Sugar in the syrup sweetens the oranges and preserves them by drawing out moisture.
- Double-refined sugar
- Refined sugar sweetens and thickens the marmalade and preserves the filled oranges in the new syrup.
The step that matters
Boil the marmalade until clear and transparent. Sugar must dissolve fully and the mixture must reach a thick set over low heat. Too little cooking leaves it runny, while overheating can scorch the sugar and darken the flavour.
