    Wild Plum Jam in a jar A classic jam is a simple, trust wild plum recipe using Prunus americana. American wild plums are a lot different from plums you might see in a store. They're tannic, sour, and generally difficult to work with if you're expecting your wild fruit to be sweet.

    A lot of times, people have the tendency to just cover up any tartness by applying extra sugar, and, while I understand, I have a hard time cooking anything with equal weight of itself in sugar. Commercial jams are way too sweet for me, and I generally don't like cooking with them.

    Wild plums from Minnesota

    A bowl of ripe wild plums. This when they'll be the best for jam and preserving.

    So, what I came up with is this jam, it's got enough sugar to be shelf stable, but it takes a nod from Magnus Nilsson's method for jam in Faviken, which uses minimal amounts of sugar.

    I also use some unsweetened pectin for that traditional jam texture, but make sure you use unsweetened as pectin with added sweeteners (sometimes it's not readily advertised on the package) will destroy the natural flavor of jams, in my opinion.

    Venison Ribs with wild plum glaze

    Plum jam, vinegar, sriracha and butter make a fantastic glaze for meat, especially smoked venison ribs.

    What you end up with is a tart, fruity wild plum jam that's versatile enough for you to cook with it. My favorite so far is using it as a glaze for meat, mixed with a vinegar ferment from the skins and pits of wild plums, a little sriracha, and a knob of butter. It was excellent with venison ribs, but I'm sure you can figure out other, creative ways to use it. You can, of course, spread it on toast too.

    Wild Plum Jam

    Basic jam made from wild plums (Prunus americana) (Base recipe yields 2 pints) You will need about 6 lbs of wild plums.
    Prep Time30 mins
    Cook Time20 mins
    Course: Snack
    Cuisine: American
    Keyword: Jam, Wild Plum
    Servings: 2 Pints
    Author: Alan Bergo

    Ingredients

    • 1000 grams (2.2lbs) wild plum puree see method below
    • 650 grams (23 oz) sugar
    • 25 grams (4 teaspoons) powdered unsweetened pectin, preferably cuisine tech brand
    • 15 grams (1 tablespoon) fresh lemon juice or ½ teaspoon citric acid powder

    Instructions

    • Make a puree of wild plums by heating them in an oven until hot, or gently warming in a covered pot with a film of water to prevent scorching. Do not cook and mash the plums like typical plums or you will release extra tannins from the skins. You can also freeze very ripe plums, thaw and mush them around in a bowl.
    • Cool the plums until you can handle them, then mash them in a bowl, adding a cup or so of water to help release the puree. If you have really nice, large wild plums, you may not need all of the water, if your plums are small, you may need more.
    • Mush this puree through a collander over a bowl to catch the skins and stones, then reserve the puree that passes through the holes. Allow the puree to cool, then measure out what you need.
    • Mix the sugar and pectin, then puree with cool plum puree in a blender. Transfer the mixture to a stove and cook on medium, and then high heat, whisking constantly, until thickened. Beat in the lemon juice, then transfer to jars and can in a water bath for 10 minutes.

      Alan, I'm so happy to have found your site and can't wait to try to make wild plum jam from our trees LADEN with fruit this year like no other year in the past. We've been in this house (Bay Area of CA) 25 years, and I've always referred to these trees as "junk plum" trees, and the fruit as a nuisance that we have to clean up. This year, a friend told me to taste the fruit, and I was astonished. It was so good. When I eat the raw fruit I also eat the skin, and the skin isn't so bad, but I'll believe you when you suggest removing it before making the jam.

      I have a question about pectin, but I'm not sure there's an answer other than buying commercial pectin for this recipe. But here goes. When I make lemon marmalade from my Meyer Lemon tree lemons, I put saved seeds inside a tiny cheesecloth bag into the first boil of the lemons, and I remove it (and squeeze it) before I add sugar and other fruit. The seeds seem to add enough pectin (and I do know citrus has pectin than other fruit). I am trying to figure out if I can adapt this for these plums (boiling lemon seeds into the mixture).

      And yes, I'm rating your recipe even before trying it. Thanks.

        Hmmm. I can't speak to that, I trust my pectin so much that I don't really try out too many crafty ways to set jam--sounds like a really interesting one though.

          Thanks for the reply. I bought pectin. :). I'll use your oven method tomorrow and am looking forward to the results.

            Hello. I saw your comments and Alan's response. I wonder if homemade pectin from apple scraps would be useful? My wife had a recipe for an apple pectin that she made from an old Haralson apple. She would use the less than perfect apples. She just washed them well, cut out any bad spots and the occasional worm, coarsely chop them up skin, flesh, seeds and all, and add to a big pot of water. I think she then boiled it all for a long while, then dumped it into a colander lined with cheesecloth to strain overnight. As I recall, the pectin was transparent, and may have had a light pink color, probably due to the skins. I know there are some recipes on the internet, and they look simple. Good luck.

        In the Book “canning for a new generation” by Liana Krissoff, She uses a method where she uses 2 small granny Smith apples per 3 pounds of plums. Apples are peeled, corEd and diced. Put these in a jelly bag and boil with plums, and the apples will serve as your pectin. Apples are then removed prior to canning. I haven’t tried it yet!

          A nice, old-school variation.

      Over 60 years ago, my Great Grandmother came over to the house in St. Paul that my family had just moved into, and spotted some plum trees in the back yard. What I can remember is that the plums were small, and there were thorns on the trees. But Lulu went out and plucked a big bowl of these ripe plums, and proceeded to make plum jam from them. While I didn't pay attention to the process, I have a memory of these small glass jars with the jam, with paraffin on top to seal them. When my mom cracked open the first one the next day and put it on toast for us, it was wonderful. It had that tart sweet flavor that I love to this day. I have had similar jams, like wild beach plum jam out on Cape Cod, but never a good, tart plum jam. Now, on walks through some nature areas hear in Cottage Grove, I think I've found some wild plum trees. Right now (July 24, 2020) they are showing green fruits, roughly 3/4 inches and more eliptical in shape. They do look like those I have found in photos on web sites, and I know that Prunus Americana is supposed to be hardy and even native to these parts. The question is, does my description match what you have seen, and if so, should I expect these little guys to get a bit larger? I hope so, as I want to try the jam on some venison. Thanks, and stay safe. Steve

        Yes, you'll see some in those areas, they're widespread in the metro area Steve.

      I have never made jam from the wild plums that are all around our house (NM), but this year there were so many that I thought I would give it a try. As you mentioned, no bush has the same taste! My problem is that the batch I am making now is impossibly tannic: makes you pucker up! Not nice. Is there a way to reduce the tannins ? I have added sugar but I don't want to add a lot as I prefer a tart jam. (ps. using apples for pectin and not canning, but freezing).

        Did you follow my directions for extracting the coulis (bake or freeze) from the plums before you add the sugar?

      Made this last week- very good. I heated my plums in the oven for about 30 min and pressed through a sieve. Then I put the scraps in the oven for a little longer to try to extract even more stuff out of them. Using it on toast for now but I’m excited to see what other things I can use it for. I have the scraps in a jar and I’m making your wild plum vinegar now, so we will see how that tastes too!

      I moved to a property south of Madison WI 8 years ago, and one of my first experiments was making jam from the wild plum bushes. I had never seen wild plums before, or made jam before, but hey. I cooked them until I could squeeze out the seeds, pureed it all, and added more sugar than I normally would, but still got a very tart jam, which was fine, and different. The next time I did this, I found a reference in an old book about adding baking soda to cut the acid in less-than-ripe persimmons, so I tried adding a bit to my simmering mixture. Yowza! All this green foam bubbled up in the pan as the acids were neutralized. I titrated soda in a bit at a time until it didn't get quite so foamy. It seemed to give me the same flavor with a little less sugar.

      A couple of years ago I fermented cranberries in honey and that worked out really well--at first the cranberries were tart-sweet and fruity, and after about a year on the shelf got a distinct alcoholic tang. I think that might be a good thing to try with plums as well.

        Nice. Yes, cranberries can be fermented in pure water too, it's known as vottlingon.

      Thanks for these ideas. I love the candied plums. I added lots of ginger root. The leftover juice makes a wonderful shrub. I think the finished plums taste very much like cooked apricots. I think that candied plums might be good served with manchego cheese and some wine. The plum jelly came out lovely. What a great gift!
