I helped make rhubarb-and-orange jam today. :P
We haven't got as much growth of rhubarb this year, so needed to supplement it with some Seville orange marmalade mix.
I chopped up the rhubarb, then stirred it while it came to the boil, then again after adding sugar.
5 big jars, 1 little jar filled. :) Left by the kitchen window to cool now.
Needless to say, there was much spoon-licking and bowl-scraping afterward!
