Also spied some really delicious looking ruby grapefruit, which shall become a unique jam - I'll share more when - if that new combo with secret ingredient becomes successful.
First, plum jam. This is a tried and tested recipe - the last time I made it was some months ago - 7 to be precise, since I just opened the last jar from that jam session a few days ago. Got a little anxious that my stash of home made goodies was nearly gone! I had left it in the far corner at the back of the fridge to see how long it would keep. I'm glad to report it was in perfect condition.
So here's the recipe:
- Plums - about 1.2kg
- 600ml red grape juice
- 2 tsp of crushed green cardamoms (in muslin bag)
- Granulated sugar about 1kg (or 450g for every 600ml reduced pulp)
Method:
Remove the pits and roughly chop the plums. Place in pot with the grape juice, cardamoms. Bring to boil and simmer for 1h. Discard cardamom.
Sieve the reduced pulp and measure the volume.
Add 450g sugar for every 600ml pulp
Stir till well dissolved and bring to a roiling boil
Allow to boil for 10-15min, stirring occasionally to prevent sticking
Boil till gel point or 105C has been reached
Bottle into sterilised jars.
