Blackberry and Raspberry Jam

Conserve, preserve, bramble, foraging, award winning jam maker, easyHaving read about the early bramble season I could wait to go our local park to see if I could find any blackberries last weekend. Sure enough there were ripe blackberries but not in huge quantities so there was a lot of pain to gain because of course the big lush blackberries are always the ones that are completely out of reach! After buying my daughter an ice cream and watching her play in the park we came home with our booty (I say we, my daughter really has no interest in blackberries)! The following day I found myself in another part of town and found a hidden pathway next to some allotments which was virtually overgrown with swathes of blackberries far bigger and juicier than the booty from the previous day. With no bag on my I found an old but fairly clean polystyrene cup on the ground and used that to pick many more blackberries with my 2 children waiting patiently asking when we could go home! I remember my mum picking blackberries as a kid and I expect I didn’t join in either! On one occasion she fell into the brambles by the side of the road on a sloping embankment (so I blame my genes)!

When I came home I knew I had to make jam (yes this is my guilty pleasure) but wanted to make one with some raspberries that I had in the freezer. Not wanting to drown out the raspberry flavour with the blackberries I knew I need to have an equal quantity of each fruit. As I only had 310g of raspberries that is what dictated the quantities of this recipe which will make 2 average sized jars of jam. So please feel free to scale this recipe up if you have more fruit, the timings may be affected though!

So what was the jam like? Well my son was my first guinea pig and he nodded his head madly before he could speak with a mouth full of scone. Then I garnered my husband’s opinion (who hates fruit with bits in) who said it was really nice and would be even better if I had sieved it!! I was really impressed with the rich colour and the intensely fruity taste which was delicious on a scone!

A rich and fruity Blackberry & Raspberry Jam - delicious!
Recipe type: Snack
Cuisine: British
Serves: 2 jars
  • 310g Blackberries
  • 310g Raspberries (I used frozen)
  • 2 tsp Lemon juice
  • 50 ml Water
  • 620g Granulated sugar
  1. Put blackberries, raspberries, water and lemon juice in a preserving pan (or very large pan) and bring slowly to the boil.
  2. Reduce heat and simmer for 15 minutes or until fruit is soft.
  3. Add sugar, stirring over a low heat until it has all dissolved.
  4. Bring pan to a rolling boil and time for 6 minutes.
  5. Take pan off heat and put a few drops of jam on a chilled plate and plae in fridge for a minute.
  6. Push your finger through the jam and if it feels jelly like and forms a crinkle then it is ready.
  7. If not put pan back on heat and boil for another 2 minutes and so on.
  8. Skim any scum off with a spoon.
  9. Ladle the jam into sterilised warm jars and put lids on immediately, if using cellophane put waxed discs on and allow to cool before adding cellophane lids.
  10. Label once cool.
Put 2 small plates in the freezer before you start.
Sterilise jars by washing in hot soapy water or dishwashing, filling with boiling water, emptying and then placing in oven for 20 minutes at 140°C then leave in oven until jam is ready. Washed lids should be sterilised with boiling water and then left to drain.

    I really enjoy jam but find the seeds get wedged into my cavities and require dentist like tools to remove them. Is there a way to puree this type of fruit so the seeds don’t get me every time?

    1. Camilla

      Herbert I think you just need to sieve it but you’d need one of those large cone style ones I imagine!

  2. Maya Russell

    Love the dark, rich colour of the jam.

    1. Camilla

      Thanks Maya:-)

  3. kelli hagenow

    How do you store them after canned? How long will they be good canned ?

    1. Camilla

      Hi Kelli, I keep all jams in a cool dark place after making and in the fridge once opened. The jam should last a couple of years I believe but it never lasts anywhere near that long in our house and particularly this one as it’s my favourite;-)

  4. bev

    Ooooh – going to have to try this!

    1. Camilla

      Great, I’ve just used up the last of ours!

  5. Lorna Craig

    This is this year’s plan, there are so many brambles about 5 minutes walk from my home! That’s if I get there first! Really looking forward to it, it’s been so long since I had any

    1. Camilla

      I get a thrill each year picking brambles:-)

  6. Abigail Cullen

    This jam look really good, will plenty of fruit, yummy!

    1. Camilla

      Thank you:-)

  7. Fuss Free Helen

    You are rapidly becoming the queen of jam Camilla!


    1. Camilla

      Excuse me while I just try and squeeze my head through this door:-)

  8. Paul Wilson

    I’ve got a few raspberries and lots of blackberries in the garden at the moment – have to see if there’s enough to make some jam!

    1. Camilla

      Good luck:-)

  9. Carolyn Clapham

    It sounds good to me, but I’ll definitely have to sieve it if my husband is going to eat it. 🙂

  10. gouldie7

    Looks great! My blackberries are taking an age to ripen this year, and my raspberries didn’t bother!

    1. Camilla

      Thanks:-) That is strange as it’s been such an early start to the bramble season this year!

  11. Maddy

    The bushes seem to have a bumper crop this year, so will have to get busy!

    1. Camilla

      It has in deed been a bumper year:-)

  12. Florence Cross

    We have plenty of blackberries this so I think I’ll have a go at making my own jam this year.

  13. Alison Turner

    This looks lovely I have just started making my own jam this year so will have to give this a go 🙂

  14. Jeanne Horak-Druiff

    Oh how true it is that the fattest blackberries are always JUST out of reach!! 😉 I always take along tall hubby and his long arms! Lovely simple jam recipe – thanks for sharing and for linking to me.

    1. Camilla

      Thanks Jeanne:-) Last year a had a hiker’s stick with me which was really useful for pushing branches out of the way, sadly I lent it out and it got broken so just me and lots of scratches this year!

  15. Paul Wilson

    Seasonal too!

  16. Lucy Parissi

    I have many scars from trying to reach for blackberries but luckily both my kids get very competitive whenever we go picking in the park. I love blackberries so much – keep meaning to post some recipes but can never find enough of them. Luckily you can buy them now! This jam looks so delicious – especially with some homemade bread – yum.

      Yes picking brambles does come with quite a lot of pain and scratches but I suppose it all adds to the experience! No pain, no gain as they say!

  19. Stuart Vettese

    Great way to use those bountiful rasps and blackberries. And of course, Scottish berries are the best 🙂

    1. Camilla

      Yes I expect all the rain you get makes them plumper:-)

  20. Jen @ Blue Kitchen Bakes

    Gorgeous colour to the jam, I need to get foraging soon though it’s been tipping it down on and off today, maybe next weekend instead!

    Thanks for linking to my muffins 🙂

    1. Camilla

      Thanks Jen, we managed to avoid the rain today:-)

  21. Heather Haigh

    I too have some raspberries in the freezer – had a fabulous crop this year but nearly finished now. Blackberries just coming so I will have a go at this when they get a bit more plentiful. It looks a lovely rich colour – can’t wait to try it.

    1. Camilla

      Thanks Heather, hope you enjoy it:-)
