Using Frozen Raspberries For Jam Recipes

Steps:

• Toss the raspberries, sugar and lemon zest and juice in a medium saucepan to combine, then mash slightly to release some of the berry juice. Set aside for 10 minutes to allow the raspberries to macerate and the sugar to dissolve. Meanwhile, place a small plate in the freezer to chill; this will be used to test the doneness of the jam.
• Place the saucepan over medium-high heat. Bring the mixture to a boil and then reduce the heat to medium, stirring frequently. Continue to cook until the jam becomes thick and syrupy, about 25 minutes. To test doneness, place a small amount of the jam onto the chilled plate and freeze for 2 minutes. Drag your finger or spoon through it. If the jam holds its shape and thickness, the jam is done; remove from the heat. If it's runny, continue to cook and test again in 5-minute increments. Once the jam has reached the right consistency, transfer to jars and cool completely before storing, covered tightly. Jam will keep in the refrigerator up to 6 months.

Steps:

• Use a very large pot.
• When the jam reaches a full rolling boil it will double in volume.
• Heat mashed berries until they reach a full rolling boil.
• Boil 2 minutes.
• Add sugar.
• Stir well.
• Bring to a boil, stirring constantly, boil for 2 minutes.
• Remove from heat.
• Beat with rotary beater for 4 minutes
• Pour in sterilized jars and seal.

Steps:

• Before you start, sterilise your jars (see tip below) and put a plate in the freezer to chill. Tip half the raspberries into a preserving pan and add the lemon juice. Mash the berries to a pulp over the heat with a potato masher, then leave to cook for 5 mins. Tip the cooked berries into a sieve over a bowl, then once all of the juice has drained off, firmly work the pulp through the sieve with a wooden spoon until you are left with just the seeds.
• Tip the juice and pulp back into the preserving pan and stir in the sugar. Heat gently, then add the remaining whole raspberries. Bring to the boil, then boil rapidly for 5 mins. Remove from the heat and drop a little jam onto the chilled plate. Now push your finger through it - it should wrinkle and look like jam. If it doesn't, boil for 2 mins, then test again.
• The top of the jam may look like it has sediment on it, but I find that if you stir it well as it cools, a little of this disappears. Pour into the jars and seal. It will keep unopened for a year, although the lovely bright colour will darken a little. Once open, keep in the fridge.

Steps:

• Combine freezer jam pectin and sugar in a large bowl, stirring until well blended.
• Add crushed raspberries, stirring to combine.
• Continue stirring mixture for 3 minutes.
• Pour jam into clean jars or freezer containers, leaving 1/2 inch head space.
• Let stand until thickened, about 30 minutes. Label jars. Serve immediately, refrigerate up to three weeks or freeze up to one year.

Steps:

• In a medium saucepan, combine raspberries, sugar, lemon juice, and salt and bring to a boil over medium-high heat, stirring until sugar dissolves.
• Cook, stirring often and mashing berries with the back of a spoon, until mixture thickens to a jam-like consistency, 6 to 8 minutes. Strain through a sieve, if desired, then transfer to a heatproof jar and let cool completely. Refrigerate up to 1 week or freeze up to 3 months.
