Concord Grapes Jam

How to Make Easy Jam | Concord Grape Recipes
Ever since I discovered that I can make my own Jams at home, it has become an addiction. Though at times I still do tend to buy store bought jams, the amount of satisfaction I get while whipping up my own is unmeasurable! It had been a while since I made a batch and I was itching to give something new a try. I saw these Concord Grapes in the local store last week. I remembered this one recipe I was hoping to try and am I glad I did!

Its sweet and its slightly tart and its has the MOST AMAZING purple blue color. From what I read online, Concord Grapes (from Concord, of course!) are less sweet than regular grapes and which you can skin easily. You can give a slight squeeze at one end and you will find the pulp readily leaving their skins. These are mostly used for their juice, Jams and jelly - remember Welch? They are also used for making pies and tarts.  Due to the fact that they have large seeds they are normally not used for eating just as they are.

The thing that caught my attention about this recipe was that it used the grape skin too for making the Jam. Also there is no pectin or water added to it. Its downright minimal as far as the ingredients go. Just grapes and sugar!. Also the sugar is warmed in the oven in order to prevent the jam from cooling when it is added.

Ingredients
  • 3 lbs ripe Concord Grapes
  • 3 cups Sugar (see Tips)
Tips
Sugar: The book suggests using additional 1 cup (total 4 cups) if you prefer your jam sweeter. I used only 3 cups and for us it was quite sweet already.
Method
1
Wash the grapes well in cold water.

2
Pick the Grapes off their stems.

3
Squeeze them out of their skins into a stainless steel pot. Its totally fine if  a little skin stays stuck to the pulp.

Its a cumbersome process indeed but it doesn't take as long as you might think. The book suggested something on the lines of 15 minutes. For me, inspite of distractions galore from a little one trying to whisk the grape from the table to trying to capture photos, it took only 30 minutes.

Set aside the Grape skins. You will be using them later.

Alternatively while the jam was coming to a boil, warm the sugar in an 150F oven.

How to check if your Jam is done?

1. Temperature Test – If the temperature (using a candy thermometer) shows 220ºF (or 104ºC), then the Jam is done. Make sure that your thermometer is placed vertically and the bulb is covered with the jam. The bulb should NOT touch the bottom of the pan.
2. Spoon Test – This is similar to how you test a sugar thread consistency.  Take a cool metal spoon and dip it into the boiling Jam mixture. When you life the spoon, if the Jam runs off the spoon like a syrup, then the Jam needs more cooking time. But if it is heavier and drops like slate/sheet off the spoon instead of flowing as drops, you know that the Jam is done.
3. Refrigerator Test - I mostly use this method to check the doneness of my jams. I keep a plate in the freezer and remove it when I want to test. I then pour a small amount of the boiling jelly/jam on this plate and let it sit in the fridge for few seconds. If the mixture gels /mounds and wrinkles when you push it with your finger, it's done. If runny and it does not have a body to it, then continue to cook the jam for few more minutes until it clears the nudge test.

    How did I never think about using a blender? Thanks for the idea Ruth and Stu, I will definitely do that.

    To Michelle; I cooked the skins and they did not get soft and the jam needed to be chewed. I wrote about this and I was told to cook them longer and they would soften. Then I read a comment today that if you put the skins in a blender with a cup of the sugar and puree them they contribute fantastic color and flavor and no chewy skins….I like that addition to the recipe.

    I made the jam and the only thing I did differently was put the grape skins in the blender with 1 cup of the sugar which turns them into a lovely purple liquid with a few tiny flecks of skin. I added the skin liquid to the strained pulp to boil together to make the jam. Also added 2 tbsp of fresh lemon juice. Intense wonderful flavour and colour.

    I’m going to attempt this recipe some time this week, my neighbor just gave me a bunch of concord grapes today! I have one question, what happens to the grape skins in the jam, do they just cook down and get soft? Thanks!

  6. Gene

    Thanks for the recipe – works well with my home grown Concord grapes. They are smaller (more time consuming) than the store bought ones but very tasty. I also cut back on the sugar as I prefer a less sweet jam.

  7. Bert

    Someone asked if the recipe could be doubled. I actually tripled it and the only problem was it was a bit unwieldy to handle the volume in the pot and keep it stirred up from the bottom. Doubling will work find and not be as much as a problem.

  8. Isabelle

    Can this recipe be doubled?

  9. DK, I have made your jam again, the first time I tried this recipe was Oct 14 2012, I am a pro at it now thanks so much. I now make it in 9 pound batches and my grape vines know they are needed now :) I have taken the time to learn how to professionally prune them. Thanks again for this recipe.

  10. Alexis

    Made the Jam and it turned out great. But I am wondering how long this will keep when canned?
