Tsuyu is a flavourful and versatile stock. The goodness of shiitake mushrooms is highly concentrated and blended with our own soya sauce. The additional of organic mirin creates a deep and delicious savoury flavour with a hint of sweetness. In fact tsuyu means “plum rain/rainy season” in Japanese, what better than a comforting and steaming bowl of noodles and tsuyu while the rain batters against the kitchen windows?
