Sushi doughnuts are a thing now

First there was latte art, then Cronuts, ramen burgers, sushi burritos, rainbow food and rolled ice cream. Now, the latest hyper-visual Frankenfood to take over your Instagram account: Sushi doughnuts.

"I'm aware that it's not the most practical way to eat sushi," says Sam Murphy, 24. The Melbourne-based vegan cookbook author says she invented the dish last summer, just playing around with a doughnut mold. But in the past week, it's gone viral in the United States, with several restaurants attempting the dish. Expect it to rapidly surpass the sushi burrito in Instagrammability.

There's Project Poke Co. in Fountain Valley, Calif., which tops them with salmon, cucumber and cabbage. A South Carolina restaurant, Oktopi, has a similar recipe. Combining two trends, California Sushi Donuts is a pop-up project that dyes the sushi rice rainbow colors. Square Fish in Toronto calls it "Doshi."
