Sweet Chestnut Jam recipe. Storing sweet chestnuts
I always associate sweet chestnuts with late autumn. And darkness. As a child, there were men on street corners selling chestnuts from glowing braziers, piling them into tiny paper bags. I always wanted my mother to buy them for us. And when she did, I didn’t like them. I’d peel one as we walked along, hoping that I’d suddenly find them delicious. But I never did. The floury texture put me off. I think I probably forced one down as it was the ritual that I liked. Watching the man rake the nuts across the grid, the warmth of the brazier and most of all being out after dark.
Being out after dark seemed so grown up. When my sister and I were thrown out of the Brownies, for disagreeing with Brown Owl, we found ourselves in the centre of Cambridge surrounded by street lights and illuminated shop windows. I can still remember the heady sense of freedom, heightened by the fact that we were out at night alone.
Finally, in my twenties, I nibbled a marron glacé one Christmas and fell helplessly in love. Sugar and chestnuts are a winning combination for me. A glimpse of beautifully packaged marrons still tempts me to do terrible things. I have eaten an entire box, without sharing. Or even feeling guilty.
When we saw men roasting chestnuts in Como last weekend, I decided to search for sweetened chestnut recipes on my return to England. I found five recipes for Chestnut Jam. Three Italian, two French. I couldn’t understand why there weren’t any more until we started to peel them. Only attempt this recipe if you are not rushing to put on the Sunday roast. Danny lost most of his nails and lasted 20 minutes of the 120 minute shelling session.
We studied the five recipes, and extracted the ingredients and method that we though would work best. I’m tired, it’s two in the morning and the Chestnut Jam is sublime. Having thought “never again” during the peeling stage, I’m now planning another batch.
It is a jam in that it’s spreadable. It is more of a delicious purée. It is probably just too special to spread on toast. Although I know that a spoonful of this would salve that 4 pm yearning for something sweet. This would be good in tiny pastry cases under a thinly sliced apple topping, or folded through whipped cream for an chic dessert.
If you have a glut of sweet chestnuts and want to store some, they can be frozen, complete or unshelled. Just put them in a freezer bag. Remove as much air as possible and freeze.
Sweet Chestnut Jam recipe
Ingredients:
- 1.5 kilos of fresh chestnuts (buy and prepare at least 1850 gms to allow for bad ones)
- The zest of a large lemon
- 800 gms white granulated sugar
- I vanilla pod
- 200 ml water
- 100-200 ml rum (depending on taste. We used 200 ml)
Method:
- Shell the chestnuts carefully to avoid breaking the inner skin (see Tricks and tips below).
- Put them in a saucepan with the lemon zest. Cover with waterBring to the boil and simmer for an hour until soft.
- Remove chestnuts in small batches from the hot water, with a slotted spoon, and peel the inner skin. The nuts need to be warm to be peeled easily. Discard any hard of bad ones (these are much harder and dark inside).
- Press the soft husks through a sieve and set aside.
- In a clean saucepan slowly dissolve the sugar and water over a low heat. Stirring constantly.
- Add the vanilla pod and the sieved chestnuts. Bring to simmering point and simmer for twenty minutes. Stirring every now and then to stop the mixture burning on the base of the pan.
- After twenty minutes add the rum and simmer for a further ten minutes, string constantly.
- Remove the vanilla pod.
- Ladle into warm sterilised jars. Label when cold and store in a cool dry place.
Tips and tricks:
- Buy more chestnuts than you need. We had to discard 250 gms out of the 1500 grms that we had bought at the first peeling stage.
- We found that the best way to peel them was to insert a small knife carefully under the skin at the top of the nut and work down towards the base. If you can then remove the base the peeling process is much easier.
- When the chestnuts have softened it’s easy to remove the skins if you snap the nuts in half, the skin should easily peel away. We found that the nuts that were still hard were the bad ones. Discard these as they would taint the good nuts.
- Don’t try and skip the sieving. Bunging the chestnuts in the blender takes out the air and you need a light pile of sieved chestnuts to add to the syrup.

Hi Cottage Smallholder,
farmingfriends is very pleased to receive some of this jam and just can’t wait to try it. I think that having read this post I might just have to try it right now!
thank you.

Hi Sara,
We mix this with whipped cream and meringues as a desert. Yummy.
Try cutting a little cross in the chestnut shell and boiling for 5 mins. Shells should come off easily.
Hi Andy,
That’s a great tip, thanks.
I’m making this delicious jam from your recipe for the second year running. Last year I introduced it to my neighbours in the little hamlet in the Charente France in which I live,although they use chestnuts frequently as a savory ingredient they had not tried it before as a sweet jam, they enjoyed it so much that this year I have been brought 10 kilos of the most beautiful glossy nuts and have now started on the marathon task of shelling ,skinning, sieving etc, so far in the first kilo I have only found 3 black nuts. However I would really like to know the best quantity of sugar to add to a given quantity of puree, some recipies say equal quantities . Last year I guessed and it tasted fine but didn’t keep well out of the fridge so I would be really pleased to have some advice.
I live in the Montagne Noire, near Carcassonne, where sweet chestnuts used to be the staple and kept both animals and villagers going throughout the winter. Chestnut jam is made in large quantities here and the favourite way to eat it, especially for the children, is to spread it on crepes. I’m currently translating several recipes given to me by the villagers. They dont seive their chestnuts. I write a monthly column for three magazines. Can I direct poeople to your website for recipes? Thankyou, Rosie Whitmore
Been looking for a recipe other than stuffing or cake so after an afternoon making the usual I found that I still had plenty left. Have tried this and found that it was indeed delicious even if it has taken a lot of manhours to make so I am off with the two boys to go and hunt for some more as it is well worth the effort
To Rosie Whitmore
I would love to have your recipes for Chestnut Jam ,I would be happy to have them in French as I expect I will be able to translate them with my neighbours help. What magazines do you write for? Are they available on line? At the moment I’m busy making herb jellies using the Apple Jelly recipe on this site ,most sucessful and, once I had explained that you don’t usually spread sage jelly on biscotte , much enjoyed by the resipients.
Does anyone know how to make the glacee chestnuts?
I am definately trying this jam to use for christmas cookies, I think it will be unusual and delicious. Thanks for sharing your talents!
Hello Marybeth
The chestnut jam is a bit of a palaver to make but it’s delicious. Great Idea using it for Christmas cookies.
There’s a good recipe here for glacee chestnuts/marron glace
http://recipes.epicurean.com/recipe/16834/marron-glace-(candied-chestnuts).html
spent this afternoon at Bisley (N.R.A.) collecting a three gallon bucket of ‘castanea sativa’; will probably attempt the above recipes, but was really there to collect nuts to propagate new trees to form my own Sweet Chesnut avenue.
Your marron glace recipe is perfect, and now, if possible – another request . . . do you possibly have a good (delicious) recipe for nesselrode pie?
I would be forever grateful, and my memory of it
as a child has yet to be duplicated from the
recipes I have tried. Perhaps you have a more
authentic one??? Thanks so much – and I will
definately be trying your chestnut jam!!!
Having pickled and preserved virtually everything around – I set my eyes upon a local sweet chestnut tree ignored by everone except the street cleaners. What a waste. As most were too small for marrons grace I decided to try your recipe. Worth all the bother and by far (excepting my fresh raspberry!)one of the most delicious ‘jams’ I have ever tasted. I’m not worried about shelf life as I don’t expect it will be around for very long. Next year I’ll be waiting under the tree. Thanks! PS a friend suggested filling merangues with the jam and fresh cream, we’re trying tomorrow and that will finish off my last jar.
Hello, I wonder if you could clarify something for me please – when you say that you can freeze whole unshelled chestnuts, would you be able to roast them after that? If so, would you need to deforst them first? Have just picked way more than we needed, but they all looked so lovely it seemed a shame to leave them, and it would be wonderful to have them roasting on the fire at Xmas. Thank you.
Hello WG
What a lovely thought – a sweet chestnut avenue.
Hi Marybeth
I’m sorry but I don’t know what nesselrode pie is?
Hi Syl
I agree they are worth all the palaver!
Hi Liz
Yes you can freeze whole unshelled chestnuts. I reckon that it would be best to unfreeze them before roasting.
Thanks for answering, re.nesselrode pie. I always thought it was ‘English’ in origin. It is a very unique flavor, a cream pie with rum soaked fuits in it, and when (maybe not too soon) I discover the ‘best’ recipe (as my memory remembers) I will share it with you!! I really enjoy your site!!!
Sounds silly I know…but I’m trying to find out how to roast chestnuts. I know about slitting the skin but I’m not sure how long to roast them for. I’ve an Aga and I’ve tried putting them straight on the hotplate but they just burned. Can I try them in the oven and if so for how long.
If all else fails I think I’ll try your jam, it sounds great!
Hello Marybeth
That sounds delicious. Thank you.
Hi Lindylou
There’s a video an the AGA site of how to roast chestnuts in the oven
http://www.agalinks.com/food/video_clips/1176_roastedchestnutsontheaga.htm
I don’t have an AGA, sob, so can’t advise.
We roasted some chestnuts in our woodburner the other day. No chestnut pan (or at least I couldn’t find it), so we just slit the skins, double-wrapped them in foil to make a package, put the package in the embers, and turned it frequently to prevent them burning. They turned out well, though it was a bit difficult to tell when they were done as we couldn’t see them! A few were burnt, the rest were fine and peeled easily.
This recipe should come with a more forceful warning!! Must’ve sped-read it and missed the 120min shelling session part!
It’s a hell of an effort and not sure I’d do it again. The queen should issue some sort of medal or certificate for anyone who has actually made sweet chesnut jam to recognise the accomplishment!
Thanks for the recipe though
For canning purposes, what’s the approximate yield for this recipe?
Hi Carl
I don’t know exactly as I fill a range of different sized jars. I would imagine between 4 and 6 lb jars.
I had similar problems peeling the chestnuts until I found this site. She makes it look very easy and after experimenting a little, I found if you keep the chestnuts in water just simmering hot and use gloves, you can do a hundred in a few minutes

Good luck
I have just come back from the Montagne Noir where Rosie lives with lots of sweet chestnuts. So tomorrow I will attempt to make the jam!Will let you know how I get on. Great website!
Further to my mail of 14/10/09, l ‘overwintered’ my castanea sativa nuts in a squirrel-proof cage outside and then planted them in one of the cold frames in the KG and covered them with leaf mould.
We now have some 500 growing baby trees, plus some more already ‘potted on’.
The anticipated “avenue” is therefore brought a step further forward.
Watch this space!

Hi WG
Long waits often are the most satisfying when eventually everything comes together. Well done!
I have shelled my sweetchestnuts already.
Is the 1.5 kilos shelled or unshelled?
Also, if I score the skins before cooking should I still cook for one hour or reduce the cooking time?
Hi Jody
1.5 kilos is the unshelled weight. Don’t worry, just retrieve a shell, weigh and then multiple this weight by the number shelled chestnuts that you have. Scored or unscored they need about an hour cooking time so that they get really soft and floury.
painless new way to peel chestnuts!! no kidding.
