Add all of the marinade ingredients (everything other than the chicken) to a dish that will be big and deep enough to eventually fit all of the chicken thighs in to marinate.

Mix together the marinade ingredients, then add the chicken thigh fillets, and give them a really good stir so that they are fully coated in the marinade.

Cover the dish with clingfilm, and refrigerate the marinated chicken for a minimum of 4 hours, or even overnight.

Once the chicken has finished marinating, take the dish out of the fridge 45 mins before you are ready to start cooking them.

Prep your chips and keep them covered in cold water until your chicken goes in the oven.

Preheat your oven to 200°C/fan 180°C/gas mark 6

Now carefully thread each thigh fillet through the 4 skewers – the skewers should go horizontally through each fillet so that they can support the weight of all of the chicken thighs once they have all been threaded. Don’t push the fillets together too tightly, as although they need to be close together to get the desired döner effect, the fillets must have room to ensure that they are cooked all the way through; not pushing them too tightly together will allow this to happen.

Lay the onion halves flat in a deep dish that is shorter in length than the skewers so that the skewers can sit on top of the edges of the dish

Cook the chicken in the oven for 30-35 minutes.

After 30-35 minutes, take the chicken out of the oven, baste with the juices in the dish, then carefully turn the döner over so the other side is facing upwards.

Place the chicken back in the oven for another 25-30 minutes before the final stage of cooking.

Drain your chips, pat them completely dry and pour the sunflower oil into a medium sized, deep non-stick pan.

Heat up the oil on a medium to high-heat. After 5-6 mins, test the heat by carefully popping in one of the chips. If the oil starts to bubble rapidly when the chip hits the oil, then it is ready. If not, wait a few more minutes.

Once the oil is hot enough, very carefully add the chips to the pan with a slotted spoon and cook on a medium heat for 10-15 minutes for a nice even cook.

Now that the chicken has been cooking for another 25-30 mins, take out again, baste, turn over and pop back in the oven for a final 5-10 minutes.

Take the chicken dish out of the oven, baste the chicken again with the juices and allow to rest for 5 minutes before carving (vertically).

The chips should be cooked and have turned a nice golden colour by now, so carefully remove them to a plate lined with kitchen paper.

If there are any juices left in the chicken döner dish, brush them over the chicken just before serving.
