A Bit of History

Fruit jam is an ancient tradition, dating back to the earliest times. The method of preserving fruits by boiling them with sugar has been used by many cultures to extend the life of fresh produce. Raspberries and blackberries, with their rich flavors and intense colors, make this jam a popular choice not only for its taste but also for its appealing appearance.

Step by Step: How to Make Raspberry and Blackberry Jam

1. Preparing the Fruits
Start by carefully washing the raspberries and blackberries under a stream of cold water. Make sure to remove any impurities or leaves. It is important not to shake them too hard to avoid crushing them. After washing, let them drain well.

2. Layering the Fruits and Sugar
In a large pot, add a layer of raspberries followed by a layer of blackberries. Sprinkle sugar over each layer of fruit. This layering method helps to extract the juices from the fruits, resulting in a flavorful and consistent jam. Let the mixture sit for 30 minutes to allow the sugar to dissolve slightly.

3. Boiling the Jam
Place the pot over medium heat and bring the mixture to a boil. Stir constantly to prevent sticking. Once it starts to boil, remove the foam that forms on the surface. This is an essential step, as it helps achieve a clear and beautiful jam.

4. Continuous Boiling
Let the jam boil over medium heat for 30 minutes. You can check the consistency of the jam with a simple trick: take a spoonful of jam and place it on a cold plate. If it thickens slightly, it is ready.

5. Preparing the Jars
In the meantime, wash the jars and lids in hot water. An excellent sterilization method is to place them in a preheated oven at 100°C for 15 minutes. Make sure the jars are very hot when you add the jam to prevent them from breaking.

6. Packing the Jam
Fill the jars with hot jam, leaving about 1 cm of space at the top. If you opt for more effective preservation, you can add a crushed aspirin tablet on top of the jam. This will act as a natural preservative.

7. Sealing the Jars
Seal the jars tightly with the sterilized lids. Then place them in the turned-off but still warm oven to cool slowly. This process helps create a perfect seal that will keep the jam fresh for a longer period.

8. Cooling and Storing
Leave the jars in the oven until completely cool. This may take a few hours. Once cooled, store them in a cool, dark place. Raspberry and blackberry jam can be enjoyed for a few months, but it is likely to be finished much sooner due to its delicious taste!

Serving and Pairing Suggestions

This delicious jam pairs perfectly with a slice of toasted bread, cookies, or pancakes. You can also use the jam as a filling for cakes or muffins. Additionally, it is wonderful alongside fine cheeses or as a topping for Greek yogurt.

Practical Tips

- If you prefer a less sweet jam, you can reduce the amount of sugar, but be careful not to alter the proportions, as sugar helps with preservation.
- You can experiment with adding flavors such as vanilla or cinnamon for a more complex taste.
- Make sure to use fresh, ripe fruits for the best results.

Frequently Asked Questions

1. Can I use frozen fruits?
Yes, but it is recommended to thaw and drain them well before use to avoid excess water in the jam.

2. How long does the jam last?
If stored properly, the jam can last up to a year. Once opened, it is recommended to consume it within a few weeks.

3. Can I replace aspirin with something else?
Aspirin is optional. If you prefer, you can use citric acid or special preserving sugar.

4. How can I achieve a thicker jam?
Boil the jam longer or add a gelling agent such as pectin.
