Process tomatoes for shelf stable storage no canning

In this video I explain how I prepare my tomato paste so that it is shelf stable without canning. This is an idea I ran across in an interesting book about a region in France and how they prepare their food for winters there. It is called 'Preserving Food without Freezing or Canning' Here is a link to that book if you're interested.
