- 1 tbsp Chinese black rice vinegar, or good-quality balsamic vinegar
- 100g/3½oz crunchy peanut butter
- 1 tsp soy sauce
- 2 tbsp sesame oil
- 1 tsp Sichuan peppercorns, toasted then ground
- 2 tbsp peanut oil
- 8–10 small dried red chillies
- 6 spring onions, white and green parts separated, thinly sliced

- 5cm/2in piece fresh root ginger, peeled and finely chopped or grated
- 50g/1¾oz unsalted dry-roasted peanuts
- steamed rice, to serve
- For the caramel spiced nuts, preheat the oven to 180C/350F/Gas 4 and line a baking tray with baking parchment.
- Place the egg white in a large bowl and whisk until foamy. Add the rest of the ingredients and mix. Pour onto the prepared baking tray and bake for 15-20 minutes, or until the nuts are crisp. Set aside to cool before serving.
- For the peanut butter chicken thighs, mix the soy sauce, rum and cornflour in a bowl. Add the chicken and mix well to ensure all the chicken is coated in the marinade. Leave to stand at room temperature for 10 minutes.
- For the sauce, in a bowl, combine the vinegar, peanut butter, soy sauce, sesame oil and Sichuan peppercorns and mix until smooth.
- Heat a wok or large heavy-based pan over a high heat. Add the peanut oil and swirl to coat the base. Add the chillies and stir-fry for about 30 seconds, or until the chillies have just begun to blacken and the oil is slightly fragrant.
- Add the marinated chicken and stir-fry until opaque and cooked through – approximately three minutes.
- Add the white parts of the spring onions, the garlic and ginger and stir-fry for about 30 seconds. Pour in the peanut butter mixture and coat the other ingredients. Stir in the peanuts and cook for another 1–2 minutes.
- Serve the chicken and sauce on plates with steamed rice, sprinkling over the green parts of the spring onion and the spiced nuts at the end.
