What’s the difference: ahi vs albacore tuna?
Albacore tuna is the most frequently found tuna in stores, lighter in color, and milder in flavor. It’s sometimes labeled as “white tuna” as well. Ahi tuna, also known as yellowfin tuna, is typically higher in quality and better suited for searing, grilling, or served raw for sushi or poke bowls.
