I like to buy my feta in chunks as I find the feta crumbles tend to mold rather expediently....I notice though that at many groceries, the feta chunks ( imported, domestic, bulgarian, etc..) are usually floating in in a steampan filled with water, and that water at times appears brackish, muddled, and downright fetid....but that's just the appearance- maybe it's all good, but nonetheless it is a concern- Unless the water is crystal clear, I won't buy it. Is this an irrational act?
Now, when I do go so far as to purchase a nice chunk, I take it home, place it in a small tupperware container, add a liitle Brita-fied water, almost covering the top.
So feta experts, does the water need to be changed periodically? If so, should I change it everyday, every hour- Should it even be stored in water? I notice after a few days that the feta will start to lose it's character, and eventually just taste like TOFU- ie: no taste at all!!!
