CHICKEN TIKKA

600g Chicken - 4 or 5 breasts
1 hpd tbl Pataks tandoori curry paste (the KEY ingredient as it includes lots of tamarind)
1 tsp mint sauce
1 hpd tsp garlic paste
1 tsp ginger paste
2+2 tbl lemon juice (Jiff is ok)
1/2 tsp chilli powder
1 dsp spice mixture (equal parts ground coriander, turmeric, garamasala, curry powder). I use this same mix for my curries.
1/4 tsp orange food colouring (much nicer than red)
1 lvl tsp methi
1 lvl tsp salt
2 tbl veg oil
3 tbl water

1. Chopped chicken breasts into 2 or 3 pieces each
2. Mix in 2 tbl lemon juice to the chopped chicken, leave for 15 mins
3. Meanwhile mix the rest of the ingredients in a bowl (including the additional 2 tbl lemon juice)
4. Add the runny spice mixture to the chicken, cover and leave in fridge for 2 hours minimum .
5. Put 3 of 4 pieces of Chicken onto skewers.
6. Heat oven grill to highest temp and leave on full blast for 5mins to ensure it is HOT
7. Place skewers on a dish where both ends of the skewer are supported at both sides of the dish making sure the dish is deep avoid the chicken touching the bottom (ie ensure the chicken is suspended)
8. Place dish under grill (I try to get the chicken pieces about 2 inches from the grill element0
9. Cook for 4 minutes, turn once and give them another 4 mins.

Let the tikka rest for 5 mins before eating,. They freeze really well.

This recipe is actually better than anything I've eaten in a BIR.. honestly.
