BLACK MULBERRY JAM IS ONE OF A KIND AND TAKES MINUTES TO MAKE
Sugar-free mulberry jam and made without pectin and perfect for those on a Keto diet or for diabetics.
At the start of July in Ontario, Canada our Mulberry Tree is full of sweet, juicy black mulberries.
If we don’t harvest our mulberry tree of these beautiful fruits the birds will feast on them for weeks.
The mulberry tree is also known as Morus is a deciduous tree that grows in many temperatures around the world.
When mulberries grow they begin green then turn white, followed by red and finally a deep purple or black colour when ripe.
Mulberries are sweet when they are ripe and often compared blackberries although they are nowhere near as tart.
Are Mulberries Edible?
Yes, mulberries are edible and widely used in many recipes such as pies, tarts, ice-cream, wines, jams and savoury dishes too.
Black, red, and white mulberry are widespread in southern Europe, the Middle East, northern Africa and Indian subcontinent, where the tree and the fruit have names under regional dialects. Jams and sherbets are often made from the fruit in this region. Source
When we moved into our home the mulberry tree was planted however we never paid attention to it.
Our front garden was horrible and needed attention badly but so did the inside of our house.
About 5 years ago when my father-in-law was visiting and he started eating the berries from our mulberry tree.
He asked us why we weren’t harvesting the berries as they were full of nutrients and delicious.
Types of Mulberry trees in North America
From my research, there are two types of mulberry trees that grow in North America where we have the Morus Rubra on our property.
The Morus rubra, commonly known as the red mulberry, is a species of mulberry native to eastern and central North America. It is found from Ontario, Minnesota, and Vermont south to southern Florida, and west as far as southeastern South Dakota, Nebraska, Kansas, and central Texas.
When I make our mulberry jam we use a mix of the deep red and dark black Morus rubra mulberries.
The reason for this is because the red mulberries are just a bit tart but as they turn a deep purple or almost black they are very sweet.
Harvesting Mulberries For Mulberry Jam
Before the tree is left with long leaves for the season mulberry picking generally lasts for about two weeks.
Although we’ve been harvesting mulberries for years it has always been a challenge to get them off the tree.
Once you stick your hand into the leaves you are going to hear many mulberries drop to the ground.
My father-in-law recommended a tarp, cut and slit it then lay it around the base of the tree.
Once you’ve done that all you need to do is give the leaves or even the tree a gentle shake.
By doing this the ripe mulberries will fall to the ground onto the tarp which makes collecting them simple.
You can also pick mulberries from the tree without worrying you are leaving more for the birds on the ground.
This method of harvesting mulberries has worked wonderfully for us.
In a 100 g (3.5-oz) serving, raw mulberries provide 180 kJ (43 kcal), 44% of the Daily Value (DV) for vitamin C, and 14% of the DV for iron; other nutrients are in insignificant quantity. Source
In 100 grams of mulberries, there are 9.8 grams of carbohydrates, 8.1 grams of sugar and 1.7 grams of dietary fibre.
So, the net carbs would be 8.1 grams per 100 grams of raw mulberries.
Pruning Mulberry Trees
We have a mature weeping mulberry tree meaning the leaves hang like long strands of hair.
Mulberry tree trimming is simple as we aim to keep the shaping even and a reasonable length.
The idea is to keep your mulberry tree looking trim and uniform so it doesn’t have long and short strands.
I also find that when I keep trimming our mulberry tree that it helps produce bigger mulberries throughout the season.
I cut crossing branches to prevent disease and to stimulate growth when the mulberry tree is dormant.
How To Make Easy Sugar-Free Mulberry Jam
- 3 cups of raw black mulberries
- 2 tablespoons fresh lemon juice
- ¼ teaspoon salt
- 3-4 tablespoons of water
- 1 teaspoon xanthan gum (optional thickener)
- ½ cup of Swerve or Monk Fruit sweetener (optional)
- Wash your mulberries and if you want to pull the little stems off you can but I don't.
- Add them to a pot with the water, lemon juice, salt, sugar and xanthan gum.
- Stir completely and let the mulberries simmer on medium-low heat for about 15 minutes stirring often.
- Using a hand blender or masher gently mash the mulberries to the consistency you like for jam.
- Pour into a clean preserve jar and refrigerate when cool.
- Use in 15-20 days or freeze up to 6 months.
How To Thicken Your Mulberry Jam with and without Pectin
This mulberry jam recipe makes about 1 preserve jar of jam which you should eat within 20 days or you can freeze it.
If you don’t want to use sweetener you can leave that step out of the recipe.
We’ve added a bit of xanthan gum which is a stabilizing thickener that we use to make keto sauces, jam, gravies etc.
Since mulberries don’t have natural pectin if you leave out the xanthan gum it won’t be as thick.
You can add 1 1/2 tablespoons of powdered pectin to this recipe if you prefer not to use xanthan gum
