For the tandoori Masala roast cardamom and coriander in a pan without fat until it smells good. Remove and grind finely in a mortar. Mix with Garam Masala, chilli and turmeric.
For the yoghurt marinade, peel garlic and ginger and chop very finely. Mix lime juice, garlic, ginger, spice mixture and 300 g yoghurt.
Wash the meat, dab dry and cut into very wide strips. Mix the chicken strips well with the yoghurt marinade in a bowl. Cover with cling film (or in a freezer bag) and chill for about 4 hours.
Preheat oven (electric cooker: 225°C/circulating air: 200°C/gas: level 4). Line baking tray with baking paper. Spread the chicken with the marinade from the freezer bag directly on the baking tray. Bake in the oven for 10-12 minutes.
Salt tandoori chicken. Serve with lime wedges and the rest of the yoghurt. Naan bread and slices of cucumber taste good with it.
