Just something little I figured out this week.
Because I can never eat a whole 7 oz container of Fage Greek yogurt in one sitting, I always have a portion left over in the fridge. This brand of yogurt also comes without a lid & using plastic wrap is a pain.
If you have the "working glass" series, the lid will fit your yogurt. I purchased mine from Crate & Barrel for $1.50 (glass) & $ .50 (lid). I have also seen them in other shops.
p.s. The 14 oz working glass is such a useful size for storing carrot/celery sticks, keeping left over broth or making a small amount of whipped cream. It's very sturdy too, not bad for $1.95
