I tried this recipe with tacos, but decided flatbread would be nicer.First make the dough. In a large bowl, whisk 125g flour with 1 tsp baking powder, 1/2 tsp salt and 1 tsp nigella seeds, then add 95g yoghurt.
Pull together into a ball, tip on to a floured surface and knead for two minutes. Now rest in a lightly oiled bowl covered with a damp tea towel.
If you can't buy it make the tonkatsu sauce yourself: in a small bowl, mix together 30g ketchup, 1 tsp sugar, and 30 g Worcestershire sauce. Set aside.
Make the salad: in a medium bowl, slice 5 romaine salad leaves and toss with 1 tbsp mayonnaise, 1 tsp sushi vinegar, and salt until well coated. Season with additional salt if needed. Set aside.
Prepare the chicken: Fill a heavy-bottomed, high-sided skillet with about 1¼ cm of vegetable oil. Heat over medium heat until the oil reaches 180°C.
Place 2 chicken thighs on a cutting board and cover with plastic wrap. Pound the chicken with the flat side of a meat cleaver until the thighs are 4 mm thick.
On the cutting board, season the flattened chicken on both sides with salt.
Add 200g flour, 2 beaten eggs and 200g Panko to 3 separate shallow bowls.
Coat each piece of chicken in the flour, shaking off any excess, then in the egg, then in the panko. Gently press the panko into the chicken to ensure a thick, even coating.
Working in batches, carefully fry the chicken in the hot oil for about 2 minutes per side, until golden brown and cooked through.
Set on paper towels to drain and immediately season lightly with salt. Keep warm in a 70° oven
To cook the flatbreads, warm clarified butter in a large pan over a high heat. Divide the dough into 2 balls and roll each out on a floured surface to 15-20cm – the thinner, the better. Once the pan is hot, cook each flatbread for a few minutes on each side until puffed up and blistered.
Start plating with 1,5 thigh onto a flatbread. Top with about 2 tbsp of salad, a drizzle of tonkatsu sauce, sliced spring onions and coriander leaves. Sprinkle furikake on top
Serve with lime wedges alongside. Feeds 2
