This fish is also known as “butterfish”, “oilfish” or even “white tuna” but we highly recommend you stick with the FDA acceptable name of “Escolar”. Calling this fish by any other name is a fast way to commit seafood fraud.

Escolar is often called “butterfish” because of it’s extremely rich texture. Although the richness of this fish makes it a delicious addition to your menu, be sure to stick with small portions (6 oz. or less, do not feature as part of a buffet), and make sure your waitstaff uses the correct terminology.
