Compost Heap Jelly



I finally got around to making my latest batch of Compost Heap Jelly.

I did it over three days as we have been here, there and everywhere this week, but it's forgiving in it's timings ... thank goodness.


First day, dig all the rinds, peelings and various bits and bobs out of the freezer.  


Add them to a large pan, cover with water and bring to the boil before simmering for at least an hour.  It was a lot longer than that for me as I was busy, so I left the pan to it's own devices, just giving it a quick stir each time I passed.


Once it has simmered merrily away for a random length of time, carefully pour into a jelly bag suspended over a large bowl or jug.  Leaving it overnight is the best way to do this as there is less chance of it getting knocked over, especially if like me you have a tiny kitchen.


In my case the juice then spent the following day in the fridge mellowing nicely.

Then do your workings out as to how much sugar you will need to add to your liquid.  I had 800mls of liquid so I needed 600g of sugar.  I used a mixture of the sachets I had in my little stash and then half and half normal sugar and some of the jam sugar that I found in the lower cupboard.

Put your pan on a medium heat and then stir continually until all the sugar has dissolved, then bring the pan to a rolling boil, you must use a larger pan than you think you will need as this rises dramatically.  

Boil hard for at least ten minutes before testing for a set either with a sugar thermometer, or you can do the wrinkle test on an ice cold plate, which I have to do now that I have sold virtually all my jam making equipment.


Then pour carefully into sterilised jars, preferably having one with a 'button' top so that you know you have achieved a perfect seal as it cools down and pops inwards.

This time my bags of fruit scraps made four jars of Compost Heap Jelly, two for me and two for Alan, who is a huge fan of this concoction.

 Watching Pam Corbin's ... the originator of this recipe ... YouTube video of making this will probably make more sense than my ramblings.

This latest batch of mine is very citrussy and tangy and very like a good lemon marmalade, but one that cost me just the price of some sugar to make.

  1. I think I will start a Compost Jelly bag for my freezer, as this will be a lovely addition to my repertoire. I checked out the Pam Corbin video when you mentioned this recently. I will probably make berries from the freezer jam in the next couple of days, as Rosie LOVES my Bramble Jelly. I still have all my jam making equipment but I have a bigger house/kitchen than you so room to store the Maslin pan etc.

    1. It's a good idea to have peelings, cores etc saved for this. It feels like 'something for nothing' which with today's prices can only be a good thing. 😀 Bramble jelly is always tasty, and if you save a few blackberries to add your peelings bag they turn the jelly a lovely colour.

  2. Rosehip and apple jelly is tasty. I make a spiced hedgerow jelly with rosehips, elderberries, blackberries, cooking apple and lemon peels, and cinnamon, clove and mace. It is my cold remedy when mixed in hot water.

    1. I'm sure watching Pam make it makes much more sense than my description. 😄

    1. Yes, and two each. So that should keep Alan happy for a while. 😀

  5. We made hedgerow rosehip syrup once and it was delicious - probably full of vitamin C but too sweet for my tastes these days. I love the name of your jelly!

    1. The taste varies every time, which is always good. This one is very tangy and lemony. 😀🍋

  8. Yum, looks delicious. I got out the jam making pan today - when I made lemon and lime marmalade recently I liked it so much ( and it was so well behaved ) that I decided to make some more to have in the cupboard, excellent as Impromptu gifts.

    1. Homemade jam and chutneys always make good gifts don't they. I used to always send blog readers that visited us in Wales home with eggs and jam. 😀

    1. Leftovers in anything are good aren't they, they get the old brain cells whirring with me. 😄

  10. What a fantastic idea for leftovers. I have never done this, though I would not be surprised if both my grandmothers did.

    1. I'm sure our grandmothers did something very similar. Alan has his grandmothers old jam pan ... with her Christmas Cactus stood in it. ❤️

  11. I love Compost Heap Jelly and the fact that it is virtually free makes me love it even more. I won't need to make any this season I don't think as I have loads of jars of home made jam and marmalade. But I do still put my lemon skins in the freezer as I grate them from frozen on to my oven baked fish dishes.

    1. That's a really good idea with the lemon skins, I had never though to do that. :-)
