This French-style mixed berry jam is easy to make and only contains 3 ingredients. No added pectin either. This is a natural-set jam, and I think you'll be able to taste the difference. Enjoy!

juice of 1 lemon
Instructions
Rinse all the berries well.
If using fruit of unequal size, slice the larger fruits it half or quarters.
Combine fruit, sugar, and lemon juice in a large bowl. Stir well to distribute the sugar throughout.
Cover the bowl and let sit at cool room temperature for 4 hours. You can also allow the fruit to sit for longer, but if it's warm in your kitchen, place the bowl in the fridge.
If you don't have a thermometer, place 2-3 saucers in the freezer to use to check the set of your jam.
When done macerating, transfer the berries and all the juices to a wide pot.
Use a potato masher to mash up the berries as much or as little as you'd like to get the texture you want in your jam.
Bring to a boil over medium-high heat. To keep your jam sparkling clear, spoon off any foamy stuff that bubbles up and discard.
Allow the berries to boil at a full, rolling boil, stirring frequently. Juices will thicken and reduce.
After about 20 minutes, check the temperature. You're looking for 223F. If you don't have a thermometer, take one of the saucers out of the freezer and drop a little bit of jam on the cold plate. Put back in the freezer for a minute, and then push the little blob of jam with your finger. If it wrinkles up, you're good to go. If not, cook for a few minutes longer and then test again.
Once the jam is a good texture, pour into clean jars or 1 big jar and allow to cool.
Store in the fridge for up to a month. Eat on all the things.
Notes
You can use up to an equal weight of sugar and fruit if you prefer. The jam will have a firmer set and may take less time to reach temperature.
