When I first bought my home a few years ago, I made a mental list of all the things I wanted to do, renovations and such. One of my ideas was to plant some fruit trees. I chose lots of fruits… apples, peaches, pears, cherries, and a few others…and then I thought.. the side fence would be prime real estate to plant some grape vines. I really had no idea what I was doing. (I’m still figuring it out as I go, tbh), but I figured “Let’s put some things in the ground and see what grows!”
Cut to a few years later and my grapevines have FLOURISHED! I’m so pleased to say that they’re now growing and producing some wonderfully sweet grapes, enough to make pots of jam (which was the goal all along). So I figured I’d share how to make it. I canned it too, but this post will be just for the making, not for the canning. It’s more about the technique, not the recipe, since there are only a few ingredients. It’s a lot simpler than you might think, the pay off is amazing, and you’ll get quite a bang for your buck. I hope you’ll give it a try!
OK here we go. All you need is:
Seedless grapes
Sugar
Lemon juice
I do everything by weight, not by volume.
Pick all of your grapes from their stems, place them in a colander and give them a good rinse. After you’ve drained them well, place them on a kitchen scale. Once you have their weight, then weigh your sugar. You want your amount of sugar to be a little less than your grapes. For instance, I had just over 4 pounds of grapes, so I used about 3 pounds of sugar. It’s not an exact science, so you can definitely cut back a little on the sugar, especially if the grapes are very sweet. Place your grapes and sugar in a large heavy pot. Add about a cup of water, (even better, you can use any kind of fruit juice), and a few tablespoons of lemon juice.
Bring it to a slow simmer until they begin to soften, then mash them up a bit. Let them simmer on a medium to low heat, not boiling, for about 30 minutes, stirring every so often.
Now it’s time to blend everything until it’s completely smooth. I used an immersion blender, but if you don’t have one, you can carefully ladle your hot liquid into a regular blender in batches.
After it’s all blended, bring the heat back up until it reaches a slow gentle boil. Let it go for about an hour, stirring frequently, until it reduces down to your desired consistency. I like it to be very thick, similar to ketchup.
Give it a stir, then give it a taste. You want to make sure it’s tart enough to balance the sweetness. I always wind up adding more lemon because I like it to be VERY tart.
And there you have it! Home made jam from fresh grapes! Boom.
Tips:
I prefer to simmer it at a slow boil to minimize the risk of burning it. However, if you’d prefer to reduce your cooking time while you’re reducing your jam, you can crank up the heat, but you need to stir it constantly. Yes, constantly. Trust me on this one.
Like I said, using fruit juice instead of water is a good flavor booster. It doesn’t even have to be grape juice. Apple, orange, cherry, cranberry, or even pomegranate juice will all work!
Sometimes when you boil jam, the bubbles can create a foam. You can skim it off the top, or.. pro tip.. just add a pat of butter to the jam. Presto! No foam!
This jam can be canned using a water bath or steam canner. Process pints or half pints for 10 minutes.
