The best jams are always homemade. Take the time to make them, it's worth it. Making jams is not difficult and they keep for a long time. They also make a lovely gift for guests. I particularly like jams made from seasonal berries and stone fruits, whose flavours accompany me throughout the year. I love the slightly sour-sweet, cool forest flavour of blueberries. I capture this flavour in jars with this simple preparation so that I can enjoy it for a long time.

For 5x 220 ml jars of blueberry jam you need

• 1 kg blueberries

• 600 g granulated or preserving sugar

• 2 lemons, juice
