Ds and I watched Nadiya's programme where she made a salmon poke bowl with raw salmon, rice etc. It looked good and he's really keen to make it but I'm unsure about the safety of the raw salmon. I thought fish for sushi had to be frozen in order to be safe raw. She didn't mention this though. Presumably I can't use any old salmon from the supermarket. Do I need to find a fishmonger that sells sushi grade fish?
