Nagoya’s way
Hitsumabushi, eaten three ways
Hitsumabushi is Nagoya’s signature rice dish, traditionally topped with grilled eel. You divide the bowl and enjoy it three ways.
First, taste a portion plain, to know the grill and the glaze.
Next, add the condiments, such as spring onion, wasabi and nori, for brightness.
Finally, pour hot dashi over the rice for a gentle, warming finish.
