The massala looks amazing,Im trying not to dribble!

Hi all just found this site!I absolutely love curry and cannot go a week without it!
I have been trying to cook my own currys for about a year now and although they are getting better they are never really good,every time they always turn out different and Its frustrating.The trouble is I used to work as a bar manager at a social club that was owned by Punjabi Sikhs which also served Indian cuisine.the food served to customers was very nice and completely different to what you would get in a normal curry house but they also used to cook their own food which was only for the family but they used to let me try it and I have to say it completely blew me away I have never tasted anything like it before or since.
I used to watch the Indian mother and daughter in the kitchen and try to pick things up. There currys were always cooked from scratch and the meat was always on the bone.The main things I picked up were
1.Whole garam masala spices would be added to oil,ie,mustard seed,cardomom pods,curry leaves,cinnamon bark.cumin seeds and cloves.
2.Onions were then added and fried until really golden
3.Then garlic and ginger was added,then the powdered spices
4,Then fresh skinned and chopped tomatoes and green chillies it was then cooked until the oil came out
5.Meat was then added and cooked for a while
6.Topped up with water and left to simmer covered
7.Curry was then reduced yoghurt was added and ground fresh garam masala and fresh coriander.
All I can say is this sort of curry is just unobtainable its like golddust this is Indian grandmothers food although I have tried and tried to reproduce it.I think I will try and make some curries the way there made on here using base sauce as I just cannot bear to keep wasting time and ingredients trying to make this curry.
Can someone give me a link for a good base sauce please.
