Yes, and it is called sous-vide. With that said; I will show you how to do this with your rice cooker. In the video I'm going to use a different brand of cooker than the one you probably have. This brand uses a different method for cooking but they are similar in construction and purpose. The first thing I will do is show how to make sure the water inside the pot (in this case) comes out boiling hot enough as if we were doing regular searing at home. Next, we will cook our meat (beef or chicken). We will just be searing it so that all of the fat is melted off and then we will refrigerate it overnight before cooking with our rice cooker like normal since there isn't any oil present in the recipe right now as part of its instructions. Finally, after letting it cool down overnight...we're ready to serve up some yummy Sous Vide Beef!
