Orange Preserve with Rum

Thin strips of whole orange cooked with lemon and sugar, with rum added after cooling to lukewarm.

Method

Steps

  1. Step 1

    Gather the ingredients: 12 oranges, preferably unwaxed, about 2.4 kg before preparation; 1 lemon, preferably unwaxed; Caster sugar equal to the weight of the soaked, sliced, deseeded oranges; Water equal to half that prepared-orange weight, plus water for soaking; 4 tablespoons rum.

  2. Step 2

    Scrub and rinse the oranges. Prick their skins all over with a fork and place in a clean food-safe container with cold water to cover. Cover and refrigerate at 4°C or colder for 3 days, changing to fresh cold water morning and evening. Keep refrigerated between changes.

  3. Step 3

    On the fourth day drain, halve the oranges and cut each half into strips about 5 mm thick, retaining the peel and removing seeds. Weigh these prepared oranges. For each 1 kg use 1 kg caster sugar and 500 ml water. Separately halve and slice the lemon just as thinly, removing its seeds.

  4. Step 4

    Put the oranges and their measured cooking water in a wide nonreactive pan. Bring to a boil and cook for 10 minutes. Add the sliced lemon, then immediately add the sugar. Stir continuously until a strong boil resumes and the sugar has dissolved, scraping the bottom to prevent sticking.

  5. Step 5

    Continue boiling, adjusting the heat and stirring frequently, for about 30–60 minutes until the peel is tender and a small sample cooled on a plate moves slowly. Remove promptly at this point. Let cool only to lukewarm, then stir in all 4 tablespoons rum before packing. The alcohol is added after cooking and remains in the preserve.

  6. Step 6

    Transfer to clean small heatproof containers, cool promptly and refrigerate within 2 hours. Keep at 4°C or colder and use within 3 days, or freeze in suitable small containers with expansion space. Thaw in the refrigerator. These historical fruit-and-sugar proportions have not been validated for shelf-stable canning; do not store this preparation at room temperature. Discard the entire container if mould, fermentation or other spoilage appears.

  7. Step 7

    For the source’s lemon-free alternative, omit the lemon entirely. Keep the same prepared-orange weight, sugar and water ratios, 10-minute initial orange cooking, subsequent sugar cooking and lukewarm addition of 4 tablespoons rum. Use the same refrigerated or frozen storage.
