3-Minute No Sugar Microwave Jam

3 Minute Microwave Jam | The View From Great Island 1

I was noodling around in the kitchen the other day with berries and the microwave.  I was trying to develop a microwave berry crisp when I accidentally discovered this amazing jam.  I guess technically I didn’t discover it, because when I Googled it, there were plenty of others who got there first.  BUT it is new to me, and maybe to you too!  I made a little pot of jam, with no sugar at all, from a cup of mixed berries, in the microwave, in 3 minutes.  And it’s pure fruit heaven.  Because there’s no added sugar, and the jam is flash-cooked, it tastes wonderfully fresh.  And it’s instant gratification, which is always good.

And by the way, those other microwave recipes I found?  They all use sugar.    The reason there is so much sugar in traditional jams and jellies is that sugar is a preservative, and functions to help the pectin form a gel.  But for this kind of quick, small batch jam, there’s no need for it.   Your reward is an eye-opening fresh fruit flavor that you will not believe.

This works really well with berries because they break down so quickly, and the nice thing is that you can make this with just a handful.  There’s no need for peeling, chopping, or pitting.  I used raspberries and blueberries, but any small berry combination will do.  I didn’t try this with larger blackberries, or strawberries, they would need chopping and probably extra time.

3-Minute No Sugar Microwave Jam

Yield: makes 1/2 cup

Ingredients

  • 1 cup berries (raspberries, blueberries, blackberries, or a mix) rinsed
  • 1/4 tsp corn starch

Instructions

  1. Put the berries in a large glass bowl. If you are using blackberries and they are large, cut them in half. Toss the berries with the cornstarch.
  2. Cover the bowl with a dinner plate, and microwave for 3 minutes. Give it a stir. If your jam is still very runny, pop it back into the microwave for 30 second intervals. Be careful, it will get quite hot.
  3. Spoon the jam into a clean jar and let cool Store in the refrigerator, the jam will firm up as it cools.

You can also use the hot jam, right out of the microwave, as a dessert sauce over cake or ice cream.

    This is probably a dumb question, but do you microwave the fruit on High power? Thank you!

    Arrowroot is a natural substitute for cornstarch. Use the same amt of arrowroot as cornstarch in any recipe. You can buy it at most health related groceries or online. I make my own yogurt and fruit. I heat the cut up fruit and 1 tsp arrowroot and it is the perfect consistency. Similar to this jam, it lasts in the fridge for over a week. Yummy

    I whipped up some heavy cream into peaks and stirred in some broken up meringues from Trader Joes. I put a layer of the cream mixture in some dessert glasses, then a layer of the jam, then some more of the cream and fresh berries on the top. Made a yummy and easy “Eton mess” dessert :)

    Wondering if a quick, short squeeze of fresh lemon juice might give it that extra little “zing”… to the taste buds, eh?

    Can’t wait to try this!

    What a great idea! As it doesn’t contain sugar, any idea how long the jam would last in the fridge?

    Who would have thought? What a great idea. I love that there’s no sugar! It looks like it would be great over ice cream or frozen yogurt too.

    This would be wonderful on toast or ice cream. Very clever Sue, it is much nicer than all the others because there is no sugar, it’s perfect.

    I can’t believe how quick this is. I spent 45 minutes on my marmalade this weekend :) But I hope it’s worth it. You always do such a wonderful job with jams, jellies and spreads. Lovely! Hope you have a magnificent Monday!

      Thanks Tricia — I KNOW your marmalade will be worth it! , But it is nice to know you can have an instant bit of fresh jam now and then, too.

    That just looks like a little pot of heaven to me, and I can’t wait to give this a try. I have several months to wait for berry season though. Do you think it would work with frozen berries in the meantime?

        It probably would work with frozen berries, but you might have to adjust the time.

    Microwave jam is NEW to me. I think its brilliant. I serve ‘melt’ jam in the microwave to make hot fruit syrups. But I never thought to kind of reverse the action. I love it. Thanx

      Thanks Lynn — I’m sure there are cases where the fruit would be too tart and would need a little sugar. I would love to try this with rhubarb and strawberry!

    “Noodling about”. That was one of my mother’s phrases. This easy jam method is “better than a kick in the pants” too. Another one of her phrases. GREG
