To make the marinade, whisk together the honey, soy sauce, lime zest and juice, sesame oil, chilli flakes and ginger in a large bowl. Pour half the mixture into a small saucepan and set aside.
Add the chicken to the bowl, stirring to make sure the meat is well covered with the marinade and season well with salt and pepper. Chill in the fridge for 30 minutes.
Cook chicken in oven for 24 minutes at 200c.
To make the glaze, bring the remaining marinade to the boil on the hob, then immediately remove from the heat and whisk in the butter.
Drizzle the glaze over the chicken thighs and top with the sliced spring onions, sesame seeds and fresh coriander to serve.
