The OXO Good Grips Colander has holes designed to allow water to drain slowly to wash impurities and starch from rice, quinoa, buckwheat, barley and more. The water pools before draining to show when water is clear and grains are clean. The small, square holes help prevent tiny grains from falling through, and the extra drain holes in the pour spout remove excess water and keep grains contained. Soft, comfortable, non-slip handles are perfect for agitating grains, shaking out water, and pouring into pots or bowls.
