❤️ Why You'll Love This Mixed Berry Jam Recipe

• Fruity mix of 4 berries
• Made with just 3 ingredients
• Thickens naturally, no pectin needed
• Easiest jam you will ever make, in only 20 minutes
• Vegetarian friendly, sugar-free and low carb

I’ve made many jams before, but this one is definitely the easiest.  You don’t even have to bother with washing and chopping fresh berries or buying 4 different containers from the grocery store.

Simply pick up a bag of frozen berries that have a mix of strawberries, blueberries, blackberries and raspberries. They’re already cleaned and ready to use.  The rest is so easy, you won’t believe it.  After you try this method, you’ll turn your nose up at the store bought stuff and make your own from now on.

There are so many ways to use jam, in addition to a dollop on some toast or biscuits.  I’ve listed some of my favorite ways to use this jam down below, so be sure to check them out.

🛒 Ingredients for Homemade Berry Jam

• Frozen mixed berries
• Monk fruit/allulose
• Lemon

*Exact measurements are listed in the recipe card below.

🥣 Recommended Tools

• Saucepan

🔪 How to Make Your Own Jam

Add the frozen mix of berries to a saucepan.

Pour in the sweetener and lemon juice over the top, then toss to combine.

Simmer on low for 18-20 minutes, stirring often, or until the berries have broken down and the juices have thickened.

You can leave it chunky.

Or use a masher to break down any remaining berries.

Cool completely at room temperature, then chill in the fridge. 

It will thicken up as it chills.

💡 Tips for Making Jam

• Resist the urge to cook it on a higher heat, low is just perfect. 
• Stir the jam often to prevent it sticking to the bottom of the pan.
• If you have diverticulitis and can’t have the seeds, simply strain them out using a fine mesh sieve.
• If you like it chunky, like preserves, you can leave the jam as is.  Alternatively, you can mash up any berries that haven’t broken down.  If you want it completely smooth, you can puree it in a food processor.

☑️ Storage Instructions

Store in the fridge for up to 7-10 days in an airtight jar or freeze. 

🍴 Ways to Serve Mixed Berry Jam

• Spread some jam over these Homemade Waffles, Pancakes or Biscuits.
• Add some along with some homemade whipped cream inside these Crepes.
• This jam is perfect to serve on a Charcuterie Board along with some crackers.
• Swirl some into your batter the next time you make muffins.
• Add a couple of tablespoons to a basic salad dressing, to add a fruity sweetness.
• Add some into a blender with almond milk or coconut milk and ice cream for an easy berry smoothie.
• Scoop a dollop over a slice of cheesecake for a fresh and fruity topping.
• And of course there is the classic peanut butter and jelly sandwich that this jam would be perfect in!

🔄 Substitutions and Additions

• If you don’t care for the mix of berries, you can make this same recipe using 1 pound of any one berry instead.  You can also use any combination of berries that you like.  Honestly, the blend of all 4 is so nice, I would recommend first trying the recipe as is and see how you like it.
• If you don’t have monk fruit/allulose, you can use all monk fruit, at the same ½ cup.  Or you can use ⅔ cup allulose, since allulose isn’t quite as sweet as the monk fruit.  If want to skip the sweetener all together, you can use honey or sugar-free honey instead. 3-4 tablespoons should be plenty. But this will depend on how sweet your berries are.

What is the secret to good jam?

Pectin is absolutely key to getting the jam to that perfectly thick and spreadable consistency. In this recipe, I chose to use fresh lemon juice, as it acts as a natural pectin that works beautifully. The tartness of the lemon also helps to balance out the sweetness of the berries.

What are common jam making mistakes?

Excessive sweetener in your jam can ruin it very quickly. Also, if you don't pay close attention to it, stirring often, it can scorch on the bottom of the pan.

Can you eat jam on a low carb diet?

Absolutely! As long as you use one of the 4 berries, as they are low in carbs. Also using a sweetener like monk fruit/allulose or sugar-free honey keeps the carbs low enough as well.

What berry has the lowest amount of carbs?

Blackberries have the lowest amount of carbs of all the berry varieties.
