Ingredients
- 2.2 lbs blackberries (mulberry or common)
- 2 1/2 cups sugar (g)
- 1 packet fruttapec 2:1
- lemon juice
Preparation
Tip: If you prefer a more natural jam, you can replace Fruttapec with a grated apple, which will help thicken the mixture thanks to its natural pectin.
Gather the blackberries and remove any impurities.
Do not wash them under running water to avoid damaging their texture; at most, pat them with a damp cloth.
Remove the small stalks by hand.
Pour the blackberries into a tall pot.
Add the sugar and Fruttapec, mixing well.
Bring to a boil over high heat, stirring constantly.
Boil for 5 minutes, then skim off the foam on the surface with a skimmer.
Add the lemon juice and stir.
To check if the jam is ready, try the “plate test”:
Pour a drop of jam on a cold plate and tilt it. If it slides slowly, it’s ready; otherwise, extend the cooking for a few more minutes.Before jarring the jam, it’s essential to sterilize the glass jars to ensure long-term preservation.
Here’s how to do it:
– Place the jars in a pot with a cloth between them to prevent breakage.
– Fill the pot with water and bring to a boil for 15 minutes.
– Drain and let them dry upside down on a clean cloth.Pour the hot jam into the sterilized jars, leaving 1 cm (0.4 inches) of space from the top. Seal with lids and invert the jars until completely cool to create a vacuum seal.
Making homemade blackberry jam is a simple and rewarding way to preserve the intense flavor of these berries and enjoy them all year round. With just a few steps and some care, you’ll get a genuine and delicious jam, perfect for spreading on bread, filling sweets, or accompanying cheeses.
