Boy, did we have
a go-around about this around a year ago! We discussed brands, pouch vs can - taste and price per ounce, and canned tuna packed in oil vs water. Of course, that was before Starkist came out with "flavored" tuna in pouches.
I still prefer whichever brand is on sale 2 cans/$1 - and Bumble Bee is still my favorite. I prefer packed in oil, but if only packed in water is on sale ... I get that. I did run across a couple of cans of Bumble Bee packed in olive oil ... boy, did I enjoy that! But, I haven't seen it again.
Tuna salad made from the stuff in a pouch doesn't "seperate" overnight and need stirring again the next day - but I don't like the after taste, dry texture, or price of the pouch stuff.
I like tuna ... and I just don't see a tremendous difference between brands.
