How to Make It
In a bowl, combine the mirin, soy sauce, yuzu juice and water.
Pour half of the marinade into an airtight container and refrigerate for later use. Add the squid to the bowl with the remaining marinade and let stand at room temperature for at least 30 minutes or refrigerate for up to 4 hours.
Light a grill. Drain the squid. Grill over moderately high heat, turning once, until tender and white throughout, about 3 minutes. Serve hot.
Mirin is available at Asian markets; sweet sherry is a good substitute. Yuzu is available at specialty markets.
Variation The marinade is also delicious with tofu or pork belly.
Grilled whole scallions and lemon wedges.
