Chirashi Don translates roughly to 'scattered' rice bowl, and that's exactly the idea — no rolling, no cutting mats, just a bed of seasoned sushi rice topped with whatever good sashimi-grade fish you can get your hands on.
It's less a recipe and more an assembly, which makes it perfect for a low-effort, high-impact dinner. Salmon, tuna and prawns are classic, but any sushi-grade fish works beautifully here.
The sushi rice does need a little care — rinsed well, cooked properly, then seasoned with a vinegar mix while still warm and fanned to cool. Get that part right and the rest is just artful arranging.
