Preparation time: 15 minutes
Cooking time: 1 hour and 30 minutes
Total time: 1 hour and 45 minutes
Number of servings: 5 jars of 400 g

Ingredients:
- 1.5 kg of fresh blackberries (make sure they are fully ripe and free from blemishes)
- 1 kg of sugar (you can adjust the amount according to your preferences for sweetness)
- Zest of one lemon (for a fresh aroma)
- Lemon essence (about a teaspoon, adds an intense citrus flavor)

Preparing Blackberry Jam:

Step 1: Prepare the Blackberries
Start by washing the blackberries under a stream of cold water. Make sure to clean them thoroughly of any impurities. Then, let them drain in a sieve or colander. It is essential that the blackberries are completely dry to avoid diluting the jam.

Step 2: Layering the Ingredients
In a large pot, place half of the blackberries, followed by some of the sugar. Continue by adding the remaining blackberries on top of this layer and sprinkle the rest of the sugar over them. The lemon zest and lemon essence are added now. These ingredients will give the jam a special aroma and a note of freshness.

Step 3: Resting the Ingredients
Cover the pot and let the mixture sit in the refrigerator overnight. This step is important as the sugar will extract the juice from the blackberries, intensifying the flavors.

Step 4: Boiling the Jam
The next day, take the pot out of the refrigerator and place it on medium heat. Stir occasionally to prevent sticking. As the mixture begins to boil, foam will form on the surface. Use a spoon or skimmer to remove this foam, which can affect the final texture of the jam.

Step 5: Sterilizing the Jars
While the jam is boiling, it's time to take care of the jars. Wash them thoroughly with warm water and detergent, then rinse them well. You can sterilize the jars either in boiling water for a few minutes or in the oven at 120°C for 15 minutes. Make sure the jars are completely dry before using them.

Step 6: Pouring the Jam
After about 1 hour and 30 minutes, the jam should be thickened and have a vibrant color. Let it cool slightly for about 10-15 minutes. Use a spatula or a knife to keep the jar steady and avoid cracking. Carefully pour the jam into the sterilized jars, filling them nearly to the top.

Step 7: Sealing and Storing
Seal the jars tightly with the lids and turn them upside down. This trick helps create a vacuum, thus prolonging the shelf life of the jam. Cover the jars with a clean towel and let them cool completely until the next day.

Practical Tips:
- Choosing Blackberries: Opt for fully ripe, shiny blackberries. Greener blackberries may lead to a more tart jam.
- Sugar: If you prefer a healthier option, you can replace sugar with honey or natural sweeteners, but you will need to adjust the quantities.
- Variation with Other Fruits: You can add some fruits like raspberries or blueberries to create a mixed jam with diverse flavors.
- Serving: Blackberry jam is perfect on toast but can also be a filling for pancakes, cakes, or even a topping for creamy yogurt.
