I had a glut of tomatoes which I had grown at home and decided to have go at making some chutney. This was the recipe I chose and I absolutely love it. The quantities above make a huge amount, but I love it . I made it at Christmas and it is now nearly March and I still have a load of it left - great. - 23 Feb 2014
