Thank you Carolyn, I think I will try a bit of experimenting with Breaker # 2 and 3 for a start and see what results from that.
I expect so will quite a lot of other people too- who have read this whole post and want to try a bit of experimenting- it seems well worth the effort.
The only problem that I can see though- is what to do with all the pulp afterwards, as you cant realy eat it with a fresh salad as ripe tomatoes, so it looks like green'ish tomato chutney is on the cards for this winter.
