Izakaya-style Cod Hash with sake and butter

Prep everything first: chop the aromatics, measure the sake and butter elements, and pat the cod dry so it colours well.

Warm the olive oil in a large pan over a medium heat and soften the onion and garlic until sweet and translucent, about 5 minutes.

Turn up the heat and add the cod. Sear in a hot pan without crowding until a deep golden crust forms, then rest briefly.

Stir in the soy sauce and the rest of the sake and butter flavours, letting them cook out for a minute until fragrant.

Add the peas along with a splash of stock or water, then cook briskly until everything is tender and the sauce clings.
