Gochujang-glazed Cod Gratin with soy and sesame

Prep everything first: chop the aromatics, measure the soy and sesame 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. Cook low with a little smoke until burnished and infused, resting before slicing.

Stir in the gochujang and the rest of the soy and sesame flavours, letting them cook out for a minute until fragrant.

Add the cherry tomatoes along with a splash of stock or water, then cover and cook gently until everything is tender and the sauce clings.

Taste and adjust the seasoning with salt, pepper and a little acid. It should taste bright, savoury and balanced.
