Can you recommend a brand? I can't say when the last time I looked at the label of canned tomatoes.

I was under the impression the cans had to be lined or the acid in the tomato reacts with the aluminum.

I buy organic, low sodium. The only way for me.

usually my salsas go through the blender as well due to using dried chilies (yet another cooked item)

I've started making mango salsa - fresh tomatoes, scallions, cilantro, and frozen mango! I kid you not, I asked the chap in my local mexican place how he makes his, as mine was never as good (I was using fresh mango) and he told me to use the frozen as it holds up better - and he was right!

Muir Glen, fire roasted organic, they aren't much more than non-organic brands.

Question to the floor: Do you skin and seed your tomatoes?

For salsa or picante, skin yes, seed no.
