I made that a couple of years ago Boxy, it bloody walked out the door with every bugger that went through it, me and Mr RR were left with very little for ourselves. Was very nice though, and puts all those under ripe, otherwise useless tomatoes to good use.
Made it several times and cranberry vodka, I used the BBC good food recipe but used less sugar. It's quite easy but you can decide on the strength of the lemon or spirit. The cranberry vodka is very easy to make but I don't discard the fruit, pop them in a box in the freezer and put a very few on ice cream.
