My gran's been making this wonderfully tangy and sweet green tomato chutney for as long as I can remember. It's fantastic as a relish in a burger or just with cheese and biscuits.
It's a brilliant way to use up unripe tomatoes if the weather (like this year) hasn't been great for them. I picked 5kg of green tomatoes from my allotment as they were starting to get blight then made two batches of this stuff. Some will be saved for Christmas presents and some will get eaten over the year.
