Arlene,
We have a juicer attachment for a grinder. After the pulp comes out we run it thru again. Very thick, but there is still ''water.'' I would have to see how time consuming it would be to cook it down, and without scorch. Since there were less tomatoes to mess with last year, I just ran them thru the sieve.
I too mix varieties. 2012 was a very good year, lol!
Right now I'm drinking hot pepper tomato juice.
