Raspberry Plum Jam Recipes

RASPBERRY PLUM JAM

Steps:

• Combine the raspberries, sliced plums, sugar, lemon juice, and orange zest in a large heavy-bottomed pot. Place over medium high heat and stir frequently as the sugar dissolves and the fruit begins to release its juices.
• Continue to cook, stirring frequently as the jam simmers and thickens. Skim any foam off of the surface with a spoon.
• (Optional) While the jam is simmering, remove plum skins with a spoon. It is slightly tedious but I prefer the texture of the jam without the skins.
• (Optional) If you prefer fewer raspberry seeds, simply place a mesh strainer over the pot. Ladle ⅓-½ of the mixture into the strainer and push it through with a spatula back into the pot. Discard raspberry seeds.
• Once the jam is reduced and thickened (see tip above), remove from heat and ladle jam into sterilized jars. Top with a lid and screw on with a ring.
• Process jars in a water bath for 10 minutes (15 minutes for 5,000+ ft elevation). Remove from water bath and let cool. Check that lids have sealed by pressing down into the center of each one. It should not move.
• Store jam in a cool dry place like a pantry and consume within 1 year.

PLUM & RASPBERRY JAM

Steps:

• Tip the sugar into a heavy preserving pan or flameproof dish with the plums, lemon juice and half the raspberries. Heat until the sugar has dissolved, then bring to the boil and simmer for a few mins until the plums are tender. Add the rest of the raspberries to the pan.
• Place a jam thermometer in the pan, bring to the boil, then cook over a high heat until the temperature reaches 104C. Alternatively, put a small plate in the fridge or freezer until really cold. Once the jam has been boiling for 10 mins and looks thick and syrupy, turn off the heat and pour a spoonful onto the plate. The jam is ready when it wrinkles as you push it with your finger; be careful not to burn yourself. If the jam is not ready, boil for another 3 mins, then repeat test as above, until it is ready.
• Allow to cool for about 5 mins. Skim the surface of any scum and pack into warm sterilised jars (see tip below). Cover with wax discs and lids. Will keep in the fridge or a cold larder for up to 6 months.

PLUM, RASPBERRY JAM & CARDAMOM CRUMBLE SQUARES

Steps:

• Butter and line a 30 x 20cm baking tin with baking parchment, leaving an overhang so you can lift out the traybake later, then butter the parchment. Heat the oven to 180C/160C fan/gas 4.
• To make the pastry, put all the ingredients, except the vanilla, into a food processor and blitz until the mixture resembles breadcrumbs. Add a couple of teaspoons of very cold water and the vanilla, then blitz again. The mixture should come together into a ball. If it doesn't, add a little more cold water and blitz again. Press into the tin using your fingers and the back of a large spoon, then bake in the oven for 15-18 mins until pale golden. Leave to cool for 15 mins.
• Stir the cardamom seeds and the lemon juice into the jam until smooth. Spread the jam over the pastry base, leaving a 2cm border all the way round. Cut each plum half into 1cm slices. Lay these in rows, overlapping, on top of the jam.
• To make the crumble, put the flour, ground almonds, butter, sugar and lemon zest into a food processor (you don't need to wash it out first), and blitz until the mixture looks like breadcrumbs. Tip this over the plums and scatter the flaked almonds on top. Bake for about 35-40 mins until the top is golden and the plums are tender. Leave to cool completely in the tin.
• Carefully lift the traybake out of the tin onto your work surface using the baking parchment. Leave for a few hours so the fruit can settle. Cut into squares or rectangles, then sift some icing sugar over the top, if you like.
