Sweet Potato Gratin in yuzu and sesame

Prep everything first: chop the aromatics, measure the yuzu and sesame elements, and pat the sweet potato 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.

Add the sweet potatoes and stir-fry until it takes on colour and the edges catch, 4 to 6 minutes.

Stir in the white miso and the rest of the yuzu 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 cook briskly 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.

Finish with the chopped chives and serve while hot.
