Iwashi Sushi:
Fresh Iwashi can be used to make sushi, either as nigiri or sashimi. The delicate, oily texture of Iwashi pairs well with sushi rice and can be complemented with soy sauce, wasabi, and pickled ginger.

Coat Iwashi fillets in tempura batter and deep-fry until crispy. Serve with a side of tempura dipping sauce for a delightful and crunchy treat.
Iwashi Ceviche:
Marinate diced Iwashi fillets in citrus juice (such as lemon or lime), add chopped vegetables, and let the mixture sit for a short time to “cook” the fish. This refreshing ceviche highlights the natural flavors of Iwashi.
Tips to Choosing an Iwashi Supplier
