Sushi’s a low-fat, nutritious food—that is, until you deep-fry it, add cream cheese or mayonnaise, and garnish it with toppings that essentially render its health benefits useless. Now, a restaurant called Jinen in Osaka, Japan, has taken the fishy dish to unhealthy heights with a new special called “unagi butter sushi.”

Over at Eater, writer Daniela Galarza reports that diners are loving the sushi, which is made of rice, unagi (freshwater eel), and a generous pat of butter, all bound together with a rope of nori. Citing Japanese media source RocketNews24, she quotes diners' rave reviews. Apparently fans say “it feels like it’s melting in your mouth.” Considering that deep-fried butter on a stick has already been served—and savored—at many American state fairs, we’re guessing that unagi butter sushi could also make an appearance at Japanese joints in our country as well.
