Wolf Hand Roll

The food you're referring to is likely a "hand roll" that is sometimes called a "wolf hand roll" or "temaki" in Japanese. A hand roll is a type of sushi that is shaped like a cone and is designed to be eaten by hand. It usually consists of a nori (seaweed) wrapper that is filled with vinegared rice and a variety of ingredients, such as fish, vegetables, and/or egg.

The term "wolf hand roll" is not a standard term in the sushi world, but it may be used in some restaurants to describe a hand roll that is particularly large or filling. It's possible that the name is meant to suggest that you can "wolf down" the hand roll in a single bite, although in reality, most people take a few bites to finish a hand roll.

To eat a hand roll, simply pick it up by the wide end (the end that was wrapped last) and hold it so that the filling is facing up. Then, take a bite out of the narrow end, being careful not to let any of the filling fall out. You can use your fingers to hold the hand roll as you eat it, or you can use chopsticks if you prefer.

I hope this helps! Let me know if you have any other questions.
