One of the things I make for general cooking purposes is pureed
tomatoes (not canned tomato puree). Put a 28oz can of whole tomatoes in
juice into the blender, and puree it good. Then push the resulting
product through a sieve to get the seeds out. That leaves a fairly
liquid, reasonably fresh-tasting tomato puree.

Don't they sell Italian passata where you live? It is exactly the
product you describe for about the same price as a can of whole
tomatoes. Rigt now I have the Mutti brand passata here. It is
available either as a pure tomato version, or with basil added. Their
whole tomatoes are also good and not really inferior in taste even to
San Marzano tomatoes.
