Contributed by Chef Mason Rice representing Nibi (AAA Four Diamond-awarded dining experience) at FireKeepers Casino Hotel in Battle Creek, Michigan were he is the Head Chef and has been at the property for 13 years.

“This Ahi Tuna was one of the first dishes I put on the Nibi menu—it’s remained a staple ever since. The Peruvian anti cucho sauce, traditionally a beef marinade, lends amazing flavor to tuna with minimal fuss, letting the sushi grade fish shine!”

Why We Love It
Perfectly seared, sushi-grade Ahi Tuna drizzled with a bold, creamy Peruvian anti cucho sauce and topped with zesty jalapeño salsa and fresh cilantro. A simple yet refined dish that highlights the purity of top-quality tuna.

Chef Mason’s Tips

  • High smoke point oils like vegetable are essential to achieving a sharp sear in seconds without burning.
  • Keep it simple—the bold sauce and fresh salsa complement the tuna without overshadowing it.
  • Prep ahead: Both sauces stay fresh in the fridge for up to 6 days to streamline service or entertaining.

A refined, globally inspired dish where crisp-tender tuna meets tangy Peruvian flavors—perfectly suited to Nibi’s AAA Four Diamond pedigree.
