Rouxbe

I buy Trader Joe's French Village Nonfat yogurt. When the container is half empty and sits for a week or so a yellow liquid forms on top as it seems to be separating, kind of like natural peanut butter when the solids go to the bottom and the oil rises to the top. Is this liquid the whey, i wonder? I assure you its not bad or old yogurt, as this seems to happen to every container of that brand that i've bought, and before the expiration date and without changing taste of the yogurt.

Anything you buy is unhygienic, too until washed at home. Old coins can be easily cleaned, therefore plenty hygienic, and resourceful. I always encourage the thoughtful reuse of everyday items. Buying unnecessary items is just plain wasteful, adding to your carbon footprint.
