I usually get the mother-in-law to make this - I provide the fruit, she buys the sugar and we split the produce - and it's kind of appropriate as she gave me the original runners of my plants years ago, but anyway she's a bit bad at the moment so I thought I'd give it a try myself. I mean how hard can it be? So I cooked up the fruits and the sugar but after about half an hour it still didn't look as if it would set and I was getting a bit bored so I've bottled it up and am hoping for the best.
Jam-making: messy but fun.
I've learnt since that you're meant to add some lemon juice but lemons don't grow for me in this climate.
