  • 900g fruit (blackberries, plums, raspberries or strawberries), prepared weight
  • 900g golden granulated sugar
  • knob of butter



    Butter is made when lactic-acid producing bacteria are added to cream and churned to make an…


  1. Put the fruit into a preserving pan or large heavy-based saucepan. For blackberries, add 50ml of water and 1½ tbsp of lemon juice; for plums (halved and stoned), use 150ml of water; for strawberries, add 3 tbsp of lemon juice (no water); and for raspberries, add nothing. Bring to the boil.

  2. Lower the heat. For blackberries, simmer for 15 minutes; for plums, simmer for 30-40 minutes; for raspberries, simmer for 2 minutes; for strawberries, simmer for 5 minutes. The fruit should be soft.

  3. Tip in the sugar, stir over a very low heat until the sugar has completely dissolved. Raise the heat, bring to a full rolling boil, then rapidly boil blackberries for 10-12 minutes, plums for 10 minutes, raspberries for 5 minutes or strawberries for 20-25 minutes - don’t stir though – until the setting point of 105C is reached.

  4. Remove from the heat, skim off any excess scum, then stir a knob of butter across the surface (this helps to dissolve any remaining scum). Leave for about 15 mins so the fruit can settle. Pour into sterilised jars, label and seal.

This jam is fabulous! The best I have ever made. The only changes I made were: I used one kilogram of plums and sugar, I cut the plums into quarters, and I warmed the sugar in the oven and added some jam setter to it. I probably should have added a little more water. I used the plate in the freezer method. I didn't get the same quantity of jam listed in the recipe.

I have never made jam before+was always a little worried that I couldn't do it, but this recipe is absolutely amazing! I have made 3 lots of jam now ( plum x 1, raspberries x 2), ready for crimbo pressies and they have all tasted AMAZING! Thank you so so so so much. x

I am 6 years old and made this jam with my dad. It was fun to make. We used mixed fruit. It tastes good.

If you add apples to a jam recipe - is it cooking apples or dessert apples which you use?

I had 2 kilos of plums (2,000g) and adjusted the recipe accordingly. Worked great, tastes great!! I have enough jam to last until next year! I also made 3 in small jars to give as gifts. Yummy stuff.

Use this recipe, the jam turned out very tasty. It is a very easy recipe to follow.

A prize winner! I made the plum jam (left skins in) added a little ginger, thought it tasted pretty good and took first prize at a flower and produce show (embarrasing as an outsider and not from the village). Thank you GF once again!

i cooked the plums with the skin on then sieved when fully cooked it made the jam a wonderful colour. it did not set after 10 mins of boiling so i gently boiled for another 10 mins it set perfect, and taste divine.

My first attempt at jam making, having been given a huge bag of plums. Took 20 minutes boiling to set (cold plate method) otherwise fab and tastes gorgeous! Only made 3 x 1lb jars from recipe though, not 4 as stated. Maybe boiled so long it evaporated?

To yetta...yes, that's a lovely combination and the apples help it set...well, that may be the answer to MY solution, a bit of tart apple!

I had great success using blackberries with this jam today..lovely set. I find it a bit too sweet for my own personal taste..if I used less sugar and more lemon juice, would it affect the set too much?

can I make blackberry and apple jam?

Forgot to rate - need to try with other fruit before giving it a full five stars.

Haven't made jam for a couple of years and as I have a lot of greengages at the mo (which I think are tastier than other plums) I used the plum quants and timings. It caught on the bottom a bit I think greengages may have more sugar that other varieties of plums so may reduce the sugar next time. It set beautifuly though and has that amazing honey sharp flavour that greengaes have. Yum!

GinaB you should put in some pectin which can help set the jam or add some chopped apple to it while cooking to help it set (you can get pectin from tesco and sometimes the chemist)

GinaB I'm not expert on jam making but I don't think there is a lot you can do with it now. If I was you, I would use it in cooked recipes like steamed sponge or jam tarts. You might like to try it uses jam and is excellent.

Made the above blackberry version. Lovely easy recipe. Stupidly made it on a hot day 33c/91f !
