This is a recipe for a delicious home-canned orange marmalade with the tart aftertones of rhubarb. Great at any time of the day, but particularly nice for afternoon tea.
There’s a bit of work in prepping the oranges correctly, so plan to do this when you can dedicate a relaxed half hour to the prep.
You can make this with sugar, or honey, or you can make it sugar-free.
Jar size choices: 125 ml (½ cup / 4 oz) OR quarter-litre (½ US pint / 250 ml / 8 oz)
Processing method: Water bath or steam canning
Yield: 4 x quarter-litre (½ US pint) jars
Headspace: 1 cm (¼ inch)
Processing time: 10 minutes
Rhubarb and Orange Marmalade
- 4 oranges (medium-size. About 250 g / ½ pound each)
- 750 g rhubarb (about 1 ½ lbs / 8 cups cut into 1 inch pieces)
- 750 ml water (3 cups)
- 4 ½ tablespoons lemon juice (bottled. 75 ml)
- 4 ½ teaspoons Pomona pectin (15 g)
- 3 teaspoons calcium water
- 500 g sugar (white. 2 ½ cups / 17 oz weight. Or alternative of your choice -- see notes.)
- Wash the oranges. Using a microplane or similar grater, zest two of the oranges, being careful not to dig down into the white.
- Put the zest in a large pot.
- Peel all the oranges, discard the peel. Take the oranges apart and get rid of all white pith and tough membranes -- they won't get any more interesting on your toast.
- Take the cleaned orange flesh, chop up into small pieces and add them (and any juice on the chopping board) to the large pot.
- Chop up the rhubarb into 2 to 3 cm pieces (1 inch), add to pot.
- Add water to the pot.
- Put pot on a high heat burner, then when it starts to boil, cover, and lower to a simmer for 20 minutes. Stir occasionally.
- Remove pot from heat.
- Stir the calcium water into the pot.
- Mix the sugar and pectin together, set aside. (If using a liquid sweetener such as liquid stevia or honey, mix the lemon juice and pectin powder together quickly). If using sugar, add the lemon juice instead now to the pot.
- Stir the pectin mixture into the pot. If using a liquid sweetener, add it now as well to the pot.
- Put pot back on the burner and bring back to a full boil.
- Let boil for 1 to 2 minutes, stirring constantly, then remove from heat.
- Ladle into quarter-litre (½ US pint / 8 oz) jars.
- Leave 1 cm (¼ inch) headspace.
- Debubble, adjust headspace.
- Wipe jar rims.
- Put lids on.
- Process in a water bath or steam canner.
- Process for 10 minutes; increase time as needed for your altitude.
- Best after at least a week of jar time for the flavours to meld.
How to water bath process.
How to steam can.
When water-bath canning or steam canning, you must adjust the processing time for your altitude.
For stevia, Better Stevia liquid stevia was the stevia used.

- If you prefer a thick peel marmalade, then take the peel from two of the oranges, clean it of all white pith, then cut into narrow strips, and cut each strip into pieces 2 to 3 cm (1 inch) long. This manual process is a bit more work, of course — but for thick-cut fans, may be worth it when there is the time.
- If you are using frozen rhubarb, thaw first in the microwave in a jug or bowl. Then add, including juice, to the pot.
- Pomona pectin comes with a small pouch of powdered calcium for you to mix with water to make calcium water.
- The pectin powder will clump if you just mix it straight in; that’s why you mix it with something first.
- Instead of the sugar, you could use the same volume amount of granulated Splenda®, or 250 ml honey (1 cup / 8 oz), or 3 teaspoons of liquid stevia. For stevia, we’d recommend Better Stevia liquid stevia.

- None. Slightly redid pectin powder process to accommodate stevia in liquid form.

The flavours are amazing for this recipe but I ended up with quite a bit more marmalade than expected and it didn’t set! I followed all of the directions exactly except for doubling the recipe and using 4 oz jars. I filled twenty 4 oz jars and ended up with about 8 cups of marmalade left over! What did I do wrong? How can I fix it at this point?
