Blackberry & apple jam

Mmmm... what's not to like?! A traditional jam recipe for foraged fruits.

Food Outdoors


Blackberry and apple jam is a perfect foraging jam to make in late July and into September, when both fruits are in season. You need the combination of fruit as the apples contain pectin which is needed for the jam to set.

What you'll need

If you are planning to go foraging for blackberries then it is advisable to wear long sleeves and trousers for protection against the thorns. Another tip is to find a stick to hook down any branches just out of reach (or use a litter picker). Heavy duty rigger gloves are useful too for moving branches out of the way.

Our favourite tip is to make a collecting pot with holes in the lid! It’s a design we put into practise after a few incidents with small children tripping over with a pot full!


  • 900g blackberries, gently rinsed
  • 120ml water
  • 340g sour apples (peeled, cored and sliced)
  • 1.36kg sugar

This is a tried and tested recipe taken from an old Ministry of Agriculture, Fisheries and Food 1940’s publication: ‘The ABC of Preserving’.

Step #3

Combine the fruit and add the sugar.

Stir until dissolved then boil rapidly until setting point is reached. This will take around 30 mins.

Tip: To check setting point - after 15-20 minutes of boiling take a teaspoon of the boiling fruit/sugar and plop it onto a saucer. Put the saucer into the freezer for a few minutes. Remove from the freezer and push your finger up into the jam. Setting point has been reached when you see a wrinkle in the jam skin.

Step #4

While you are waiting for setting point get your jars ready.

Wash the jars and the lids in hot soapy water (remove old labels).

Rinse and then place upside down on a shelf in the oven (not plastic lids).

Put the oven on the lowest setting and leave the jars in until you are ready to pour the jam in.

Step #5

Once setting point is reached remove jars from the oven and pour or ladle the jam into the jars.

Place lids on the jars (use a tea towel to grip the jar and lid as they will be hot).

  • have fun creating beautiful labels for your jams, and maybe add a gift tag. You could write them using mushed up fruit ink
  • if you don’t fancy making jam you could make a crumble or stew the blackberries with a bit of sugar
