Freeze soups, sauces, tomato paste and herbs securely in these four ingenious trays. Built of thick silicone, each grey tray boasts half-cup, one-cup, two-cup and two-tablespoon compartments and a rim reinforced with embedded steel. The clear plastic lid keeps out odors, allows stacking, lets you see what's inside and prevents spills on the way to the freezer. Once frozen, your flavorful cubes pop out easily with a simple press on the bottom of the tray, and the lids and trays clean up easily in the dishwasher.
