I have just found and ordered from Asda ready made pots of reduced calorie jelly in strawberry and kiwi, mango, and apple and raspberry, or something like that. Thought they would make a nice change. My problem is being rural the supermarkets are all slightly smaller so don't have very good ranges.
Most supermarkets sell them - they are Hartleys Sugar-Free Jelly and are available in 4 flavours - cranberry&raspberry, blackcurrant, apple&watermelon and my all time favourite - Mango&passionfruit. They're quite expensive at full price - 60p ish per pot, but often Tesco have them on offer at 6 for £2. Not that I'm an expert obviously ;-)
Well I drove to the bigger town with a bigger tesco and I now have some of the different flavoured pots. Tried the watermelon and apple, nice. Wish they made them in the powder packets they work out so much cheaper.
