How to make greengage jam

Greengages are a type of pale green plum with sweet, juicy, golden flesh. They are fairly high in pectin and are therefore fantastic for jams and jellies. Always try to use under ripe fruit as it contains more pectin than the riper plums and is slightly less sweet which is good when using large quantities of sugar as in jam making.

Ingredients

1
Place the greengages and water into a heavy-bottomed, deep saucepan and bring to the boil
2
Simmer for 20 minutes (as the jam cooks, the stones will float to the surface – remove them with a slotted spoon as they appear) then stir in the sugar
3
Return to the boil and boil hard for at least ten minutes – the jam should read 105°C on a sugar thermometer
4
Leave to cool slightly before transferring into sterilised jars

Tip

If you don’t have a sugar thermometer to test the set, place a small plate in the fridge for 15 minutes then put a small amount of jam on to the cold plate. If a skin forms, the jam is ready to take off the heat. If not, keep boiling and repeat the process.

Variations

To add a little bit of luxury to your greengage jam, scrape the seeds of a vanilla pod in whilst cooking.

Fruity white wines such as Viognier and Gewürztraminer make an interesting, zingy substitution for the water.

Plums go well with other stone fruits like peach, nectarine and apricot so if you have an abundance of these then try mixing them together.

Serving suggestions

Greengage jam goes brilliantly with cheese, especially Gruyère, spread on crusty white bread for an afternoon treat or serve with crackers for an after dinner cheeseboard.

Gooseberry jam is also great to use in baking, try using it instead of raspberry in a bakewell tart, smothered on a scone or piped inside a doughnut.
