Peter,
Thanks for posting the research you did.I did want to add a little bit tonight.
I found the classico ground and crushed tomatoes to be a little bit more watery than 6 in 1's.They taste great,but a few pies I made a sauce using classico products,I had some problems with the water pooling into the center from the sauce,while baking.I ended up with a few pies that had a wet,watery,soggy center.I do tend to use a bit more sauce at times,but I never had a problem with water pooling until I used these cans.
For those that do not know,many times,for an experiment,I will use the canned tomato products,straight out of the can,poured into a bowl,nothing added,and use some of it for a sauce.I Usually add my oregano and garlic after the pie comes out,on top of the pie.
I do this,to help me narrow down the cans I want to work with most.That said,I really like the Classico brands in the cans.They taste great!I will do some more experiments to see if this happens again or not.
