The blackberry jam is running low and I have been considering what would be a good subject for my next attempt. What makes blackberry jam so good is its slight tartness, it is not too sweet or cloying. There has been some fantastic looking rhubarb at the Mountain Organics stall at the markets lately, lovely fresh, thick stalks. Rhubarb, like blackberries, has that tart quality which I like so much, I even eat it unsweetened on my muesli. Thinking this could potentially replenish my diminishing jam supply, I bought a couple of bunches for jamming. Rhubarb is low in pectin, so adding it in the form of lemon pith at the very beginning of cooking is essential, else it won't set. I was fairly happy with the result, its a smooth jam, with a definite tang and a soft sweetness.
Ingredients:
2kg rhubarb
1.2-1.5kg unrefined cane sugar (or any other sugar)
2 lemons
Method:
Wash 5-7 jars thoroughly and place in a low oven and place a saucer in the freezer. Its a good idea to warm the sugar up in the oven too, to prevent the temperature of the jam lowering too much when you add it. Chop the rhubarb into 1-2cm lengths. Wash the lemons and peel right down to the flesh, you need all the white pith for pectin. Chop the skin and pith into strips and tie up in a muslin bag. Juice the lemons. Place the rhubarb, muslin bag and lemon juice into a big pot, shallow rather than deep, if possible. Bring to a simmer and cook the vegetables until they are soft, about 30 minutes. Remove from the heat and add the sugar in a steady stream. Stir until disolved. Return to the heat and cook on high to reach 'setting point'. After 10 minutes or so, start testing the jam. Place half a teaspoonful on the cold saucer, push he jam with a finger, if it runs back freely, it needs more boiling, if it wrinkles, its ready. I don't like my jam too firmly set, so i generally pot it between these two stages. remove the jars from the oven and ladle in the jam. Screw the lids on tightly and leave to cool.
