Not very (ecologically) green green tomato chutney

I am having trouble with slugs and snails eating my tomatoes. I did try picking just before they were ripe, but then they started eating those!

So, Tuesday, on my day off, I picked 2lbs of green tomatoes and made green tomato chutney. It involves 2 1/2 hours simmering, so using up a lot of gas!

It smells nice, and the scrapings of the pan tasted nice - though not spicy but that will happen in the 3 months I have to wait.

I have 3 jars of chutney which should be ready for Christmas.
