You will adore this quick and Easy Greengage Jam recipe with a subtle zing of lemon. With just 3 ingredients and no pectin, it’s the perfect way to preserve a glut of these unique and delicately flavoured stone fruits.
A Life Long Love of Greengage Jam
As a child I loved Tiptree Greengage Jam which was a rare treat and usually bought by my parents from the local garden centre.
So, back in 2016, I made a Greengage Jam recipe where I cracked open the stones to remove the kernels which were added during cooking to aid the set.
Fast forward to August 2023 and I decided I could make a better and easier Greengage Plum Jam recipe.
So, this time I’ve opted for adding lemon juice and skin to add a little zing, maintain colour and aid the setting process.
Are Greengages high in Pectin?
Yes, just like plums, Greengages are high in pectin so technically you don’t need lemon juice in Greengage Jam to aid the set.
However, I found that in the time it took to reach setting point the colour changed from green to tawny brown in my previous recipe.
Hence, I almost halved the recipe and decided to add lemon to help maintain the green colour (photos don’t show just how green it was).
Choosing the best Greengages for Jam Making
Greengages are in season from August to September.
For the best colour, flavour and set, look for green, just ripe (fairly firm with slight give), greengages and not riper, soft yellow ones.
If you wouldn’t eat it, don’t jam it, is the rule of thumb!
Ingredients for Easy Greengage Jam
There are just 3 ingredients:
- Greengages – freshly picked or bought, don’t use overripe ones which won’t taste good.
- Granulated sugar – always my preference over jam sugar (with added pectin) which can give a stiff textured jam. Plus, you get a more concentrated fruit flavour as more water is boiled away.
- Half a lemon – juice and skin to add pectin, flavour and maintain colour.
How to make Greengage Jam (full recipe bottom of page)
- Add greengages and water to a preserving pan.
- Simmer for 15 – 18 minutes until greengages are cooked.
- Remove the stones.
- Add sugar, lemon juice and lemon skin and heat on low until sugar dissolves.
- Turn heat up and bring to a rolling boil. Time for 8 minutes or until temperature reaches 105°C.
- Test for set by placing a few drops of jam on a chilled saucer and place in fridge for 30 seconds. Push your finger through the jam and if it forms a crinkle/wave it’s ready. If not re-boil for another minute and test again, repeating until setting point is reached.
- Remove lemon skin and pot up jam into hot sterilised jar using a jam funnel and ladle.
- Then screw lids on immediately.
Trouble Shooting Common Jam Making Mistakes
- Jam is crunchy: you didn’t allow the sugar to fully dissolve before bring to a rolling boil.
- Jam is too runny: you misjudged the setting stage. Can be rectified by tipping jam back into the pan and re-boiling until setting point reached.
- Jam is too stiff: you boiled the jam for too long resulting in stiff crinkles when testing for set on saucer. A jam thermometer can avoid this.
- Jam burned: you didn’t stir it (been there, got the t-shirt)!
- Jam develops mould: you didn’t sterilise your jars and lids (never skip this step).
Is Easy Greengage Jam Shelf Stable?
I’ve lost count of the times that readers from across the pond ask if they need to water bath my jams to make them shelf stable.
All my jams are shelf stable as this is how we make jam in the UK and in most of Europe.
If your preference is to water bath then you’ll need to check out your jar manufacturer’s instructions for guidance.
How long will Greengage Jam keep?
Easy Greengage Jam is at its best for colour and flavour in the first 12 months.
How should you store jam?
It should be kept in a cool, dry, dark place (I keep mine in a cupboard in my garage) where it will keep and be safe to eat for years.
Once opened, store Greengage Jam in the fridge where it will keep for months, even a year.
Always use a clean teaspoon serve it which will prevent the jam from spoiling.
How many jam jars are needed?
This Easy Greengage Jam recipe makes 1 litre of jam so you can use 2 x 0.5 litre jars or 4 x 0.25 litre jars.
It’s a good idea to always add an extra, small jar, just in case a recipe renders slightly more jam.
Can you double the recipe?
Yes, you can double the recipe but you’ll need a jam thermometer to gauge when to test for set (105°C) as the time it takes to reach setting point will increase.
Ways to use Easy Greengage Jam
You can serve Greengage Jam for anything from breakfast on toast or croissants to afternoon tea on scones.
It’s great swirled into yogurt, rice pudding, semolina etc.
You can also use it in cakes, sponge puddings, cookies and jam tarts!

Easy Greengage Jam
Equipment
- Preserving pan (or similar)
- 1 Measuring jug
- Kitchen knife
- Lemon juicer
- Digital scales
- long wooden spoon
- Metal whisk
- Digital thermometer (optional)
- 2 0.5 litre jam jars with lids 4 x 0.25 litre jam jars with lids
- jam funnel
- ladle
- 2 Saucers
- 1 Kettle (to boil water for sterilising)
Ingredients
- 1 kilogram greengages rinsed
- 800 grams granulated sugar
- ½ lemon squeezed for 1 tablespoon lemon juice & half lemon skin retained
Instructions
- Before you start place 2 saucers in freezer and sterilise jars (see notes).
- Add greengages (counting them into the pan) and 150 millilitres of water to a preserving (or similar large) pan.
- Bring to a simmer over a medium heat and cook, stirring occasionally, until the stones come away easily from the flesh (about 15 – 18 minutes).
- Once greengages are cooked remove the stones with a wooden spoon. Agitating with a whisk can help to loosen and find them. You should have as many stones as you counted greengages at the beginning!
- Add 800 grams granulated sugar, 1 tablespoon lemon juice and the half lemon skin. Heat on low until the sugar dissolves, stirring with a wooden spoon until no crunching sounds can be heard. Do no simmer or jam will be crunchy.
- Turn the heat up to full and bring the mixture to a full rolling boil whilst stirring continuously to avoid the jam catching on the base . At this point time for 8 minutes or if you have a digital thermometer aim for a temperature of 105°C, stirring continuously. The jam will drip slowly off your spoon and last drop will hang on when jam is at setting point.
- Test for set by putting a few drops of jam on a chilled saucer and place in fridge for 30 seconds. Push your finger through the jam and it should form a crinkle (or wave) and feel gel like. If setting point hasn’t been reached boil for another minute at a time and repeat test until ready.
- Remove lemon skin and pot up jam into 2 x 0.5 litre or 4 x 0.25 litre hot sterilised jars.
- Screw lids on immediately.
- Allow to cool before serving. Once opened store in fridge.
Notes
Sterilise 2 x 0.5 litre or 4 x 0.25 litre jam jars and lids by washing thoroughly in hot soapy water (or take straight from dishwasher), fill with boiling water, empty and place on a baking tray. Bake in a preheated oven at 140°C for 20 mins and keep the jars there until ready to pot up. Place lids in a bowl and pour over boiling water, use tongs to lift out and drain on a clean tea towel or draining rack.

It looks fab. I make my own jam too, as it allows me to add spices or make a combination of 2 fruits. Getting the fruits from the reduce aisle is a good idea, as the fruits are more ripe and better for jam (and cheaper too).
Camilla
Thanks Anca:-) Pectin levels decrease with riper fruit and also affects the keeping quality so just ripe to under ripe fruit is best for jam making.

This looks delicious I have never had greengage jam before. Thanks for sharing my yellow plum jam recipe.
Camilla
Thanks Nayna, I am so surprised that so many people haven’t either heard of greengages or had the jam!
Fashion and Style Police
I love jam. Thanks for sharing this recipe. Definitely going to try it.
Camilla
Thanks Stella, enjoy:-)
Ickle Pickle
Oh wow – I have never heard of greengages, or made jam! Love this post 🙂 Kaz x
Camilla
Gosh, they’re rarer than I thought which is quite sad! Think there needs to be a campaign to grow more of these wonderful trees!
Kavey
I think all of us who love making jam have had that happen to us once, because you are on the side of caution and not wanting it to overcook. Love the colour!
Camilla
Thanks Kavey, yes I have done the too stiff jam and never want to go back there LOL:-)
Viki Marden
I have never heard of this type of plum before and sadly don’t like jam myself but may have to try and make some for my other half and daughter if I see any, I have always wanted to try my hand at Jam.
Camilla
That’s shame you don’t like jam and also that you haven’t heard of greengages, they taste so good!

I am always nervous with jam. I tend to get it too runny or too set. The saucer in the freezer trick seems to work as to judging readiness. We had greengage plums in the yard when we were kids.
Camilla
It is a case of practice makes perfect but I think I got so distracted with my phone that I simply forgot where I was at and started potting up before it was ready! Lesson learned, all jams will have my undivided attention from now on!
Claire Jessiman
I’m not sure I’ve ever eaten a greengage! Shall keep an eye out for them. I had to reboil a jam this week too!!
Camilla
They were far more common in my childhood and are so delicious. This was my first time with runny jam, lesson learned to not do social media whilst making jam!
Claire mason
I wish I was good at this sort of thing as it looks and sounds yummy x
Camilla
Claire I only started making jam three years ago, practice makes perfect:)
Nikki
I used to love Jam when I was younger but went off it. Your post has reminded me of how much I liked it! def on the shopping list!
Camilla
The greengages I hope LOL:-)
