Cell-Cultivated Bluefin Tuna Toro Saku

BlueNalu’s bluefin tuna toro is a 10 oz sushi-grade saku cultivated directly from fish cells, crafted with care to honor the flavor, texture, and precision chefs expect from one of the world’s most prized cuts. Positioned between chu-toro and o-toro, it delivers a balanced expression of richness and restraint—luxurious yet clean, with consistent marbling and performance. Produced in a controlled environment without fishing, antibiotics, or detectable mercury, this toro reflects a thoughtful new path forward for an ingredient that demands care, on the plate and beyond it. Designed for uniform slicing, predictable yield, and refined service in sushi and fine-dining applications.
