This mini steamer is designed specifically for microwave cooking, crafted from high-quality materials that prioritize both safety and durability. It is BPA-free, ensuring 100% food safety for all your culinary needs, and dishwasher safe, making post-cooking cleanup hassle-free. With an ideal 1-quart capacity—equivalent to 4 cups or 750 mil. This steamer is perfectly sized for a range of tasks, from reheating desserts and melting butter to warming up leftovers or heating soups. The inner walls on both sides are marked with clear scales, allowing for easy and accurate measurement of ingredients or liquids, eliminating guesswork during preparation. A key feature of this steamer is its locking lid design, which securely seals the container to prevent spills, even when it holds liquids. The lid is equipped with a grooved handle that not only makes it easy to screw on and off but also provides insulation to avoid burns when handling the steamer after cooking. Additionally, the locking lid features small and medium holes that serve 2 practical purposes: they facilitate easy pouring of excess water and help maintain moderate humidity inside the cooker during the steaming process. This balanced humidity ensures that steamed vegetables, seafood, fruit, and meat stay tender and flavorful, enhancing the overall taste of your dishes. Beyond convenience, this steamer promotes a healthier way of cooking. Material: Plastic.
