A bit of history:
Blueberry jam is not just a recipe but a tradition passed down through generations. It has been used by many cultures as a method of preserving fruits, bringing not only sweetness but also a way to take advantage of a bountiful harvest. Blueberries, rich in antioxidants and vitamins, add a boost of health and vitality, and jams have always been a way to keep the essence of summer in every jar.

Making blueberry jam: Step by step

1. Picking and preparing the blueberries:
If you have the chance, pick the blueberries from nature. Use a special comb to gather them gently. Make sure they are ripe and free of defects. If using store-bought blueberries, choose fresh ones with uniform color and no blemishes. Wash them well under cold water to remove impurities.

2. Preparing the ingredients:
After washing the blueberries, it's time to remove any leaves or twigs. Place them in a large container. In another bowl, prepare the sugar: leave it in the fridge overnight so that it is cold and dissolves more easily in the juice.

3. Boiling the blueberries:
In the morning, add the blueberries to a large pot or cooking tray over low heat. Sprinkle the sugar over the blueberries and stir gently. It is important to simmer on low heat to avoid burning the jam. Let the mixture boil for about 60 minutes, stirring occasionally.

4. Testing the jam:
To check if the jam is ready, take a plate and drop a few drops of the mixture. If the drop holds its shape and does not run, the jam is perfect. If not, let it boil for a few more minutes and repeat the test.

5. Preparing the jars:
Meanwhile, wash the jars in warm soapy water, rinse well, and place them in the oven at 100 degrees Celsius to sterilize. This step is essential to prevent bacterial growth.

6. Sterilizing the lids:
The lids of the jars should be cleaned with a piece of sterile cotton or dressing soaked in sanitizing alcohol or brandy. This detail ensures proper sealing and optimal preservation.

7. Filling the jars:
When the jam is ready, carefully pour it into the hot jars. Seal them tightly immediately after filling. Cover the jars with a thick blanket to help them cool gradually, preventing the glass from cracking.

8. Storing:
Let the jars cool completely, then store them in a pantry, away from sunlight and heat. This way, you will always have delicious blueberry jam on hand, perfect for serving on toast, pancakes, or with yogurt.

Useful tips:
- If you want a thicker jam, you can add a little lemon juice, which not only helps with preservation but also adds a note of freshness.
- Another delicious variation is to add a few sprigs of rosemary or mint during boiling for an unusual flavor.
- Blueberry jam pairs wonderfully with goat cheese or as an ingredient in a cheesecake.
