Well this past Monday, "Presidents Day" I decided to make the rounds in the North Dallas area for the elusive 6-in-1 crushed tomatos. I went to different Krogers, Albertsons, Tom Thumb, Central Market, Whole Foods and none had any. They all had pretty much the same stuff, "Hunts", "Heinz", "Contadina", "Progresso", and their own store brand. So I'm resolved that I won't find that brand here unless there is some little Mom & Pop market that might have them. I did find a new Krogers that had the San Marzano brand, pretty pricey though.
I have tried Contadina and wasn't too jazzed with that brand. My last batch, and sorry I forgot the name but was some premium crushed tomato in Albertsons that I thought was pretty good. I guess my next batch I'll try Progresso, haven't tried that brand yet.
Also when I was looking for stuff I checked on the flour types too and it looks like it is KA bread or Gold Medal bread flour are my only choices, I'm sure those are fairly equal too.
