Oh thanks Lisa, thats a great help. I then follow the recipe you previously posted!
I will either do this next weekend or the one after. Do you know how many jars this fills? I saw in a local cook shop regular jars that were over £1 each. I know this was a little wasteful but for 25p in Tesco you can buy cheapy marmalade... so I just threw the marmalde out and cleaned the jars up. As it was the cheap stuff they hardly used any glue on the labels so they just came clean off with some soapy water.
i will sterilise these before filling!
