The Sistema Microwave Collection Rice Cooker is conveniently designed to cook rice, polenta, and couscous in the microwave. The rice steamer includes a pressure chamber plate that allows any overflow to be collected and then drained back into the base chamber. It also comes with a lid with cool-to-touch, easy-lift tabs, and a nonstick rice spoon. Made from 100% virgin plastic, this BPA- and phthalate-free microwave rice steamer is dishwasher-safe when placed on the top rack, microwave-safe with the vent open, and safe for storing in fridges and freezers.
