Orange Marmalade 4 0 5 5
  • Prep: 1 min
  • Cook: 8 hrs
  • 1 min

    8 hrs

    8 hrs 1 min

  • Yields: Make 4 jars


4 oranges

1 lemon

3-4 cups sugar

3-4 cups water

1 - 2 packets jamsetta or setting agent ( if needed)


1Wash, quarter, and seed the oranges and lemon separating the peel from the pulpy center, and cutting the peel into very small shards. Or chop the whole oranges and lemon in a food processor until chunky (just make sure you dont over-process). Transfer the pulp and peel to the slow cooker and add the water Cover and cook on HIGH until simmering, about 2 hours.


3Add the sugar and jamsetta if needed and mix well: you want the sugar to equal the amount of boiling orange stock. Stir often until you are sure the sugar has dissolved. Then cover, turn the cooker to LOW, and cook for 6 hours, stirring every 2 hours to check for consistency. The peel will be translucent when the marmalade is ready for the next step.


5Remove the lid, turn the cooker to HIGH, and cook for another 1 to 2 hours, or even longer (It can cook for up to 6 hours more), until you have a nice syrupy consistency.


7Ladle the warm marmalade into clean spring-top glass jars (or use screw tops with new lids); let stand until cool. Store, covered, in the refrigerator for up to 2 months or serve warn right out of the crock pot!

Hi Mike

I didn’t “ignore” your previous comment as you assumed
You left it at 2.44am my time
I’m human. I sleep. haha Sorry if that’s unreasonable to you

You should try kindness and understanding before trying to accuse people of things they didn’t do – it doesn’t make you a nice human.

Happy slow cooking 🙂

Further to my previous (ignored) comment, my attempt at this is approaching 10 hours in the slow cooker. It hasn’t changed its appearance since I added the sugar after 2 hours. I’m going to turn it back to low and leave it overnight before finally deciding to dump the whole thing. Not impressed.

Got this recipe on the go at the moment. Since I added the sugar to the fruit after two hours ( and just over two hours ago) nothing much seems to be happening. I’m still trusting the process and realise it’s got another 4 hours on low before the next stage, but when might I start to see it coming together?

My first brew was appreciated by all. This time, because it gobbled so quickly I’ve doubled the amount. I’m using Chai seeds to thicken rather than lots of sugar. I like my to be slightly tangy.

Well, I started wrong. I forgot to add the water to the crock pot until it was already cooking for over an hour… Oops. I added some water and cooked a little more than another hour. Then I turned down to low. After 4.5 hours I couldn’t tell a difference in terms of thickness so I cranked up to high and took off the lid. After about another half hour (probably less) it still wasn’t simmering and I knew it might not finish before bedtime. At that point I just dumped it into a saucepan and finished it on the stove. Looks delicious! Thanks for the recipe.

This looks wonderful but I wonder if you can water bath it for 10 minutes so it will keep longer than 2 months.

I made this yesterday, The taste is wonderfully rich. I added just a pinch of cinnamon to ours. It was nice to be able to leave it for a bit and run errands as opposed to stirring it non stop.

Tasty! Simple to make but took total of about 11 hours in my slow cooker as it didn’t seem to thicken that much, but was still a nice consistency once in the fridge. I did a double recipe in my 6L slow cooker.
I used the quick preparation of chopping the whole oranges in the food processor 😊

This marmalade produced an awesome fragrance through my small home. At tgat point i thought to add a cinnom stick or 2 and a couple star anise and some clove buds. (This comforting smell reminds me of winter Christmas in the States) I think because it was cooked on this manner I did not encounter the usual burn to the pot like I have in the past…being a busy mum it’s easy to get distracted… I like this method and I would make it again. And yes it does take a while to reduce down. I doubled the mix and made in a 5.5litre Big W brand slow cooker…
