My mum gave me another batch-worth of empty jars today so I'll have to return them to her all filled up. While my husband, when on form, can go through a 250ml jar a fortnight, I hope I'll have enough altogether to last us for a year and enable us to supply our family and friends with some orangey delight as well. This year we ran out two months ahead of schedule. I had no idea of my husband's capacity for home-made marmalade - it's twice the capacity for shop bought!!
