This sauce is made with shiitake mushrooms cooked in a creamy sauce with tamari. The sauce is thickened with kudzu, a Japanese starch used to thicken sauces. It is available in supermarkets, Asian grocers and health shops. It makes the most beautiful, smooth and glossy sauce. But if you can’t find kudzu, use cornflour.
