We remove sinews and tenderize the meat fibers by pounding it. This is a time-consuming task, but we cannot cut corners. A single missed sinew can ruin the shape of the fried meat and alter its texture when eaten. Breadcrumbs and Frying Oil: We use fresh breadcrumbs made daily from bread baked according to a specified recipe. These are unique Mai-Sen breadcrumbs, differing from commercial ones in content, size, and shape. Our frying oil is also a Mai-Sen special order. We carefully fry while adjusting heating times. The glossy, crispy, and fluffy expansion of the coating, which Mai-Sen calls 'ken-dachi,' is the pride of Mai-Sen's tonkatsu. Sauce: Mai-Sen currently produces four types of sauce: sweet, spicy, for sandwiches, and for Kurobuta (black pork). The basic recipe has remained the same since our founding, with skilled craftsmen inheriting the founder's dedication to carefully adjusting the taste using fresh vegetables and fruits as ingredients.
