Many restaurants in the UK erroneously sell this dish as ‘prawn katsu’, which is wrong and stupid because katsu means ‘cutlet’. In Japan ‘prawn katsu’ is a kind of prawn (shrimp) patty, breaded and deep-fried like a schnitzel – the prawns themselves, given the same treatment, are simply called ebi furai: fried prawns. But I guess that doesn’t sound Japanese enough, or something. Anyway, it doesn’t really matter how Japanese they are, or what they’re called. They’re just delicious, simple as that.
Ridiculously not difficult
