How to make Easy Greengage and Apple Jam

Greengage and Apple Jam is simple to make and a delight to eat.  Serve the jam spread on bread, toast or scones.  Use it to fill a cake or include it in a yogurt dessert, there are so many ways to eat this jam.

What are Greengages?

Greengages are a member of the plum family and one of the less well-known British fruits. Look out for them in supermarkets and markets in late August and September.

Don’t be deceived by the green colour, they are ripe when they are green.  Greengages are known in France as Reine Claude, they are sweet enough to be eaten raw when fully ripe.

You can use greengages in the same way you would any kind of plum. They have high pectin levels so are ideal for jam making.

Why add apples to the Greengage and Apple Jam?

I added apples to this recipe because I only had a small number of greengages and wanted to make the most of them.  Apples are often added to jam to increase the pectin which helps to make the jam set.  However, greengages are high in pectin so they are not needed for this purpose.

If you have a lot of greengages you can make the jam without the apples.  Simply substitute the weight of apples with more greengages.

How much jam will the recipe make?

You will get two standard  450 g jars of jam from this recipe and a little bit over.  The ‘little bit over’ is the cook’s perks, let it cool and you can do your own taste test.

Can I double the quantities to make more jam?

You can double the quantities of ingredients to make more jam.  You will also need to increase the rolling boil time.   Please be aware that this recipe has been tested for the amounts stated on the recipe card and I cannot guarantee the results for a larger batch. 

How do you sterilise your jam jars?

I sterilise my jam jars and metal lids by thoroughly washing and rinsing them.  I then put them, still wet, upside down onto a baking tray and place it in the oven at 150C just before I start to make the jam.

The water creates steam which helps to sterilise the jars.  I take them out of the oven and fill them with the hot jam, then put on the lids.  There are other methods but this is how I sterilise my jars.

How to make Greengage and Apple Jam

Wash, stone and quarter the greengages. Peel core and slice the apples.  Now you are ready to make jam

Put the greengages, apples, and water in a large pan and simmer until soft.  Add the sugar and lemon juice and stir until dissolved. Bring to a rolling boil and boil until setting point is reached.

What does a rolling boil look like?

I  learned about jam-making from my mother and grandmother.  A lot of what you learn in cooking and baking is very visual.  It’s much easier to understand when you can see what you are aiming for.  So here is a little help with the main techniques for jam making. The video below will show you what a ”rolling boil’ looks like.

The Wrinkle Test – how do I know if my jam is set?

Once the jam has boiled, you will need to check if it will set (firm up) once cooled.  There are many different ways to test for setting point.  You can use a jam thermometer, you can use the ‘flake’ test, but I have always used the wrinkle test.

You need to place some saucers in the fridge before you start making the jam.  Then once you have boiled your jam for 15 minutes, take the pan off the heat and put a teaspoon of the jam onto one of the cold saucers.

Place the saucer in the fridge and leave for 5 minutes.  Then remove the saucer and push your finger across the jam.  If it wrinkles, you can skim off the froth and pot up your jam.

My Jam didn’t wrinkle – what do I do?

If you haven’t got a wrinkle, put the pan back on the heat and boil for another five minutes, then test for set on another cold saucer.
