Why it works: Sweet potato and miso share more aroma than cooks usually use. They rank in the top 7% of all ingredient pairs, and 6 recipes mention both. Both carry 2,3-pentanedione, which smells butter, sweet. The science ↓
The recipe
Serves 2Ingredients
Contains: soy, sesame (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Heat the oven to 425°F (220°C). Toss the sweet potato wedges with a little of the extra vegetable oil, spread them on a baking sheet and roast for about 25 minutes, turning once, until crisp and tender.
Whisk the miso paste, hot chilli sauce, mirin, lemon juice and the 1 tbsp vegetable oil in a bowl until smooth.
Spread the miso mixture over both steaks, cover and refrigerate while the potatoes roast.
Toast the sesame seeds in a dry frying pan over medium heat for 1 to 2 minutes, shaking often, until golden. Set aside.
Heat a little oil in a heavy frying pan over high heat. Cook the steaks 3 to 4 minutes per side until an instant-read thermometer reads at least 145°F (63°C) in the thickest part, then rest them for 3 minutes.
Slice the steaks against the grain. Pile with the crispy sweet potatoes and watercress, and scatter over the toasted sesame seeds to serve.
