How to select the best Tuna for the Blackstone Seared Ahi Tuna
Ahi tuna is best served seared on the outside and rare on the inside. As such, you want to select fresh or flash frozen tuna. Look for Ahi tuna that labelled as sushi grade. While this may be a bit of a misnomer, as tuna fish is not actually graded, it does indicate that the fish was likely handled in a way that it is safer for eating rare. Tuna that is deep red in color and shiny is an indication of quality tuna. Avoid tuna that looks pale, discolored, brown, or dry as these are indicators that the tuna may not be very fresh.
Making the Everything Bagel Seared Ahi Tuna
To prepare the dish you just need to make a quick Avocado sauce and prepare the tuna. Sautéed veggies are an optional side for the seared tuna as well.
