hi adrian have you tried using butter ghee to cook this recipe. this can give a rich aroma and taste to the dish, providing you don't burn the ghee ie frying at too higher temperature. try this....
add 4 tbsp melted ghee to the preheated pan medium heat then add 1 tbsp of finely chopped onion fry for a couple of mins until the onions starts to soften then add 1 chefs pinch of fine chopped garlic fry until raw smell cooked out 20 secs max then add the salt 1 pinch, 1 1/2 tsp kashmiri chilli powder or to taste 1 tsp restaurant masala(curry powder mix) 1tbsp tomato paste (2/1 tom paste water) turn up the heat to high mix well the when you smell the spices release their aroma add the 1st ladle of base sauce mix well and then reduce then add 1 chefs pinch of methi and another ladle of base 1 tsp lemon juice mix well then add the precooked chicken. turn down the heat to medium and simmer until the sauce starts to thicken slightly (if it thickens too much just add a little more base) 1 minute from the end add a good pinch of fine choppped coriander mix in well, turn off the heat and serve garnished with some more coriander.
