The yellowfin tuna (Thunnus albacares) is a species of tuna found in pelagic waters of tropical and subtropical oceans worldwide. After caught, these tunas are processed, cleaned hygienically to maximize the freshness and optimize the texture. Yellowfin tuna has a mild, meaty flavour that's leaner than bluefin. Yellowfin tuna populations are less threatened and more abundant than bluefin tuna making these an eco-friendlier choice. Additionally, these yellowfins are an important commercial tuna species, particularly the raw sashimi market. In Japan the term saku means block. Saku is commonly served as maguro in sushi bars. Because of its uniformity, it is preferred by Japanese chefs for sashimi and other sliced presentations. Ideal for making ahi sushi or for pan searing, this premium yellowfin saku is boneless and skinless with blood line removed.
