Most of my tomatoes did ripen in the end and I have harvested the last of them and put the green ones in brown paper bags with bananas to ripen them). They haven't tasted as good as last year and I'm not sure why. We haven't had a lot of rain, but they taste a little watery. perhaps because I have had to use a hose and they have had too much at any one time. So to intensify the flavour I have roasted them in the oven with my home-grown garlic and thyme and a bit of olive oil and salt.
I then put the roasted tomato mixture in sterilised jars. I'll be testing some of it tonight with pasta.
