What Is Escolar Nigiri?
Escolar nigiri is a type of sushi made by placing a slice of escolar (a deep-sea fish) over a small mound of vinegared rice. Sometimes, it may be garnished with soy sauce, ponzu, or finely chopped scallions to enhance its flavor.
Escolar, scientifically known as Lepidocybium flavobrunneum, is often referred to as the “butterfish” or “white tuna” due to its luxurious, oily texture. The fish is naturally high in wax esters, which give it a smooth, almost creamy mouthfeel when eaten raw.
The Origin of Escolar in Sushi
Escolar is not native to traditional Japanese sushi culture. In fact, it became popular in the United States and other Western countries in the late 20th century, when sushi chefs began experimenting with less common fish to meet growing demand.
Because of its affordable cost, visual similarity to white tuna, and melt-in-the-mouth texture, many sushi restaurants adopted escolar as a staple for nigiri and sashimi. However, its rise was not without controversy, as we’ll explore later.
The Taste Profile of Escolar Nigiri
One bite of escolar nigiri is enough to understand why it is often called “the butterfish.”
- Texture: Smooth, silky, and rich. Almost feels like eating butter on rice.
- Flavor: Mild, slightly sweet, and clean-tasting compared to stronger fish like mackerel or salmon.
- Aftertaste: Very subtle, without the lingering fishiness some seafood can leave behind.
