Oh, how I wish we could grow raspberries in Sydney!  Our temperate clime precludes this, and as a result, a punnet of  fresh raspberries (150g) usually costs $9 or more.  Thankfully, frozen raspberries are widely available, and at $11 a kilo, they’re a reasonably economical option.

We’ve never made a straight raspberry jam before, but inspired by a jar of homemade Tasmanian jam that we were given recently, we bought two boxes of frozen raspberries to give this a go.  Pete loves raspberries, and wanted to make a jam which would set with less sugar, so as to not mask the tartness of the berries.  To achieve that, he used three jars of our homemade pectin, which led to a firm but not rocky hard set (even after a night in the fridge) – feel free to use less if you’re happy with a softer jam.  Berries are low in pectin, so they normally require quite a bit of pectin and sugar to set.

Pete’s Raspberry Jam

  • 1.4kg frozen (or fresh) raspberries
  • 1kg white sugar
  • 3 x 300ml jars of homemade pectin (use less if you want a softer set)
  • Juice of 1 large lemon
  • 2 teaspoons vanilla syrup

1. In a large stock pot, combine the raspberries, pectin and lemon juice.  Warm until the raspberries are defrosted, but don’t bring to a boil.

2.  Add the sugar, vanilla syrup and bring the pot to a gentle boil.  Skim the pot of any scum or foam that rises to the surface. Once you’ve cleaned up the surface, turn the heat up and bring the pot to a rolling boil.

3.  Boil until the jam sets.  Test by putting a small blob on a cold plate – if the jam is set, it will wrinkle when given a small poke with your finger.

4.  Ladle the jam into sterile jars and seal tightly, then process the jars in a boiling water bath for 10 minutes, ensuring that the water covers the lids by at least 2.5cm.  Note: make sure you put the hot jars into hot water – if you use cold water, the glass jars may crack.  This batch filled 6 x 300ml jars, with a little bit left over for tasting!
