Black Raspberry Jam.


Anyone who knows me knows that I LOVE black raspberries.  Maybe it’s because you can only get them for two weeks out of the year, but when those two weeks come around I will just buy pint after pint and eat until I can’t eat any more!  This year I decided that I wanted to try and prolong the happiness.  I found a recipe online for black raspberry jam, courtesy of  Incidentally, they also pointed me to a great local pick-your-own berry farm, Shenk Berry Farm.  I got the enjoyment of picking my own fresh raspberries (getting them quite a bit cheaper than in any market or roadside stand I might add) and they were delicious.

Surprisingly, the recipe to make the jam was fairly simple.  This was my first attempt at any sort of jam or jelly.  Aside from a blazing hot kitchen (no central air here!) it went very smoothly.


  • 6 cups mashed black raspberries (4 pints, about three pounds)
  • 3 cups sugar
  • 1 lemon, zested and juiced
  • 2 tablespoons powdered pectin


  • Prep 3 pint jars or 6 half pint jars.
  • Combine mashed berries, sugar, lemon zest and juice in a large pot (a wide pot is best).
  • Bring to a boil, stirring regularly.
  • Skim the foam that develops.
  • When the jam has thickened a bit and the boil can’t be stirred down, sprinkle in the pectin and stir to combine.
  • Cook for an additional 5-8 minutes, until the jam seems quite thick.
  • When the jam has thickened to your liking, remove from heat.
  • Ladle into jars, wipe rims, apply lids, and process in a boiling water canner for ten minutes.
  • When time is up, remove jars from canner and let cool on a folded kitchen towel.
  • When jars are cool enough to touch, remove rings and test seals.
  • Jam is ready to eat as soon as it is cooled but can also be stored in a cool, dark place for up to a year.


  • The taste was very good!  I was worried that this was a lot of sugar, but I guess the lemon juice sort of balances it out.  Plus, you’re not going to sit and eat jam with a spoon, it’ll be spread over whatever you’re putting it on.
  • You definitely want a big pot that leaves a lot of room.  Once the berries are boiling and start to thicken, it gets very spattery.  The deeper and wider the pot, the better.
  • There are a ton of sites online that you can find instructions on “how to can” – the basics:  wash the jars and lids in soapy water, then boil jars for ten minutes and keep in hot water until used.  Put lids in a pan of hot not quite boiled water for five minutes and use the lid lifter wand to pull them out.
