Blackberry Jam Recipe Jamie Oliver Recipes

BLACKBERRY JAM

Steps:

• Mash blackberries in a saucepan with a potato masher. Stir in sugar until juices form; place about 1 tablespoon blackberry juice in a small bowl and stir in cornstarch. Pour cornstarch mixture into saucepan.
• Bring berries to a boil, stirring often, until jam is thickened, about 15 minutes. Stir in cinnamon and allspice. Remove from heat and allow to cool. Transfer jam to a bowl, cover, and refrigerate until chilled. Stir in lemon juice.

BLACKBERRY FOOL

Steps:

• Halve, the vanilla pod and scrape out the seeds, then place in a large pan along with 350g of the berries, the sugar and lemon juice. Bring to the boil over a medium heat.
• Simmer for 3 to 4 minutes, or until syrupy and the berries are soft but holding their shape. Set aside to cool.
• In a large bowl, whisk the cream to form peaks, fold through the yogurt and swirl through a third of the syrup.
• Layer the rest of the syrup and cream in dessert glasses, garnish with syrup and fresh berries.

BLACKBERRY JAM

Steps:

• The night before you make your jam, layer the blackberries and sugar together in a very large bowl, then cover and set aside at room temperature. This helps the sugar to start dissolving so you don't run the risk of over-cooking the fruit when you actually begin to make the jam. The next morning, give everything a quick stir, then set aside again until you are ready to start cooking.
• Before you start, put a small saucer in the freezer. Take a preserving pan or a large, wide-based pan (the wider and more open the pan, the faster the jam will be ready, so a preserving pan is really ideal) and tip the berries in, scraping out all the juices and any undissolved sugar. Stir in the lemon juice, then collect all the pips and secure them inside a tea-leaf strainer or piece of muslin before adding them to the pan (cooking the pips along with the fruit extracts the pectin they contain, helping your jam to set).
• Start the blackberries over a low heat until all the sugar is completely dissolved, then bring to the boil and simmer for 5 mins. Turn off the heat and spoon a little hot syrupy jam onto the chilled saucer. Once it's cool, push it with your finger. If it wrinkles a little, it's ready and has reached setting point. If it's too runny to wrinkle, return the pan to the heat and boil in 2 or 3-minute stages, removing the pan from the heat each time you do the saucer check, until the jam wrinkles.
• Skim off any excess scum, then stir in the knob of butter, if you want - this will help to dissolve any remaining scum. Leave the jam for 15 mins before ladling into sterilised jars - this allows the fruit to settle so it doesn't sink to the bottom. The jam will keep in a cool, dark place for at least 6 months. Refrigerate jars once opened.

APPLE-BLACKBERRY JAM

Steps:

• Combine blackberries with 1/3 of the water in a saucepan over low heat. Combine apples with the remaining water and lemon juice in another saucepan over low heat. Simmer both pans slowly until blackberries and apples are soft and mushy, about 90 minutes.
• Inspect twelve 12-ounce jars for cracks and rings for rust, discarding any defective ones. Immerse in simmering water until jam is ready. Wash new, unused lids and rings in warm soapy water.
• Remove blackberries from the heat and pass through a sieve to remove the seeds, if desired.
• Remove apples from the heat and puree with an immersion blender.
• Combine pureed blackberries and apples in a large bowl and weigh on a scale. Add the same amount of sugar as the weight of the pureed fruit.
• Transfer fruit puree and sugar to a large pot and bring to a boil. Cook at a rolling boil for 3 to 4 minutes. Test for the setting point by placing a dollop of the jam onto a cold plate and pushing it with your finger. If the jam wrinkles it is ready.
• Pack jam into hot, sterilized jars, filling to within 1/4 inch of the top. Run a clean knife or thin spatula around the insides of the jars to remove any air bubbles. Wipe rims with a moist paper towel to remove any residue. Top with lids and screw rings on tightly.
• Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and lower jars 2 inches apart into the boiling water using a holder. Pour in more boiling water to cover jars by at least 1 inch. Bring to a rolling boil, cover, and process for 15 minutes.
• Remove the jars from the stockpot and let rest, several inches apart, for 12 to 24 hours. Press the center of each lid with a finger to ensure the lid does not move up or down. Remove the rings for storage and store in a cool, dark area.
