Instead of layering on hard to find ingredients, this recipe is all about the basics. In fact, besides the sweet soy sauce, all of the ingredients can be found easily at most grocery stores. The only tricky part is the cooking process, which should be done over extremely high heat, which means it's very important to not crowd the pan.
This recipe is for two portions, and I wouldn't try to cook more than this at one time. Luckily, it only takes a few minutes for each batch.
