A Fresh, Flavour-Packed Take on a Classic Fish Burger
Fish burgers are something truly special, yet they’re rarely spotted on menus these days. More often than not, you’ll need a trip to the seaside to enjoy one properly, thanks to the easy access to fresh fish. But the good old fish burger is long overdue a comeback.
This crispy fish burger with lemon caper sour cream and sriracha sauce brings a fresh, modern twist, a simple way to breathe new life into a classic.
The Perfect Sauce Duo
Between the crispy battered fish fillet and the soft, slightly sweet brioche bun lies the real magic, the sauce.
Traditionally, tartar sauce made with mayonnaise, capers and lemon is the classic companion to fried fish. Here, that tradition takes a sharper turn. Instead of mayonnaise, sour cream is blended with salty capers, fresh lemon and fragrant dill, creating a cool, tangy balance.
This creamy base pairs perfectly with a second, fiery partner, sriracha, bringing a tongue-tingling kick to every bite.
