Counter Top Chef Multi-cooker, Stainless/Black



Westinghouse SA21950


   An easy to cook soup ,rice , vegetables and more with Westinghouse SA21950 Counter Top Chef Multi-cooker, Stainless/Black  Since I'm a college student and my mom works we're both on the go, so up to this point we've only used the RICE and SAUTE modes. RICE is pretty obvious. Just set the mode to RICE, put your rice, water, etc. in the cooker, press START and the cooker will prepare it. The rice is perfect each time for us. The manual recommends cleaning the entire unit after fixing rice because of the residue it leaves behind. We use the SAUTE mode to cook frozen pre-packaged meals like "Wanchai Ferry's Complete Meal for Two" or "Bird's Eye Voila!". The most important thing you need to know if you do this is the SAUTE mode is one of the four modes where you can't control the temperature and the temperature change is determined by which food you select to cook (fish, meat, or vegetable). Regardless of which food you pick there's a good chance the Westinghouse Multi-Cooker will prepare the food faster than an average stovetop. I suggest closely watching the food you're cooking to determine whether or not you need to take it out earlier than what the food's instructions say. Other than that we haven't had any problems.
     This is a great cooker and you should be able to prepare many different foods with it. The only annoyance is the loud beep that sounds every time you push a button, but we're getting use to it. We've had this cooker since February so I'll update this review when we use some of the other cooking modes.
