I made jam today for Moe. Plum jam seasoned with vanilla and cinnamon.
Moe and I picked four pounds of plums off a neighbour's tree and I needed to do something with them. I found a recipe for Plum jam on another blog Chez Pim. I doubled the recipe using four pounds of plums and along with the vanilla beans I also added three cinnamon sticks. The jam set up nicely without any pectin and I'm really pleased with the colour. It is really pretty. If you look closely you can see the little black specks from the vanilla beans.
2lb (about 1kg) Green Gage Plums (I used yellow Plums)
1lb (about 500g) sugar
juice from 1 lemon
2 vanilla beans
Cut the plums into big chunks into a large, non-reactive pot (like a
Le Creuset), discard the pits. Add the sugar and the lemon juice. Stir
well to combine. Cut a round piece of parchment paper the size of the
diameter of the pot, and place it on top of the fruits. Let sit for
about an hour.
Cut two vanilla beans lengthwise, scrape the inside of the pods to
get to all the seeds. Scrape the pods and all the seeds into the pot
with the fruits. Place the pot over the stove and bring to a boil over
medium heat. Gently stir to make sure all the sugar is melted. Bring
the heat down to a simmer, and continue to cook, stirring occasionally,
until it reduces at least by half or until it reaches the thickness you
These plums have so much pectin in the skin that you don't need to
add any extra to get it to gel. To test to see if the jam is ready,
take a small amount of jam on the tip of a spoon, and drop it on a small
plate and spread it a little. If the jam is ready, it should gel up
nicely when it cools down. If it's still a little runny, you might want
to continue cooking for just a bit longer.
It really is that simple. If you're like me, you can just put the
jam in a large jar and put it in the fridge (discard the vanilla pods
first, by the way). It will be eaten up soon enough. If you want to
keep it longer, then get a bunch of little jam jars and follow the
manufacturer's instructions on how to fill and seal the jars so that
they are shelf-stable.
