The last two weekends at the farmers market I have found plentiful amounts of concord grapes, it’s that time of year you know. I love them, eating them right off the stem sweet and tart at the same time and an intense burst of concord grape flavor. I bought a lot of them, really way too many to eat so I decided to try my hand at making jam. I have never canned or preserved anything before, one day I will, but not this time, so this jam has to be used fairly quickly within a month or so but honestly, it’s so good it didn’t last more than a week. I sterilized some canning jars poured the hot jam in the jar, sealed and refrigerated it overnight, by the morning it was thick rich intense grape jam. I have become somewhat obsessed with making jam now, giving jars to my daughter to take home for the kids and they are really enjoying it. This weekend I made a spiced plum jam following a recipe from Hannah and her beautiful blog, Blue Kale Road, it is amazing and you should try it. Back to the grape jam though, it’s so easy to make, and you can make it in small batches. This is going to make a really good PB&J sandwich.
2 quarts (about 8 cups) concord grapes, cleaned and removed from stems
4 -4.5 cups sugar
juice of 1 lemon
Add grapes, sugar and lemon juice to a medium saucepan mash the grapes to release some of the juices. Bring to a boil on high heat, when it comes to a rolling boil reduce heat to medium and let simmer uncovered for about an 1-1 1/2 hours. You will notice it is thickening and it will coat your spoon. Drop some of the jam onto a saucer and if it thickens it’s ready.
While the grapes are simmering sterilize your jars and lids, let them boil for 15 minutes, remove to a clean tea towel to dry. When the grapes have finished cooking take a large non reactive bowl, I used an 8 cup heatproof glass measuring cup place a sieve on top and carefully pour the grapes into it. Stir it so that the liquid drips into the bowl, stir constantly and scrape the bottom of the sieve from time to time.
All you want left is the skin and seeds, push the pulp through, there will be very little left in the sieve.
Place the liquid back in the saucepan and simmer on medium for about 15 minutes. Pour into sterilized jars, screw lids on tightly and let sit until it reaches room temperature. You then refrigerate overnight or several days. It will become very thick and jam like.
