Soysauce and butter?! When I got too lazy for slow cooking, I will let rice cooker to take care of the whole meal. Rice cooker as to rice, is like oven as to bread in a logical way:D In China rice cooker is so practical that it can be used to make even chiffon cake, which I surely won't try. I used it to make mushrooms-mixed-in rice. I don't know how to name it. Fungi rice? haha..I got the recipe from Japanese website and made a twist. I put rice/different kinds of mushrooms/tuna flakes/sake(rice wine)/soysauce/water in the rice cooker and pushed the button. When it was done, I cut in a small chunk of butter, also some dried parsley and gave it a stir when the rice was still pretty hot. It turned out really good~ One of my friends told me that in Japan people put only soysauce, butter and cooked rice together to make a meal.. Do I dare to try? ><'
