Summer is the best time to make a mixed berry jam when blueberries, raspberries, blackberries, and strawberries are abundant. This jam, which is also commonly known as bumbleberry jam, is low in sugar and made without pectin or artificial flavoring. It takes only 30 minutes to make and is a must-try if you love berries.
Prepare the berries – Sort the berries and discard any moldy or spoiled fruit. Rinse briefly and drain well. Hull the strawberries and cut large ones into smaller pieces.
Combine – Add the berries, sugar, lemon juice, and salt to a large, heavy-bottom saucepan. Cook over medium heat, stirring until the sugar dissolves.
250 g Raspberries, 250 g Strawberries, 250 g Blackberries, 500 g Sugar, 2 tbsp Lemon juice, ½ tsp Salt, 250 g Blueberries
Boil – Increase the heat and bring the mixture to a boil, stirring frequently.
Mash – Reduce the heat to maintain a gentle simmer. Mash the berries with a potato masher, leaving some pieces of fruit if you prefer a chunkier jam.
Cook – Simmer for about 20–30 minutes, stirring frequently, especially toward the end as the jam thickens.
Test for doneness – Spoon a small amount onto a chilled plate. Let it sit for 2–3 minutes, then push it gently with your finger. If it wrinkles and doesn't immediately flow back together, the jam is ready.Alternatively, use a candy thermometer. The jam should reach approximately 220°F (104°C) at sea level.
Jar – Remove from the heat and ladle the hot jam into clean, warm jars. Cool and refrigerate, or freeze in freezer-safe containers.
