Last Weekend's batch cooking: Chicken Tikka masala

Here's the pic - will post recipe later.
Indegredients:
1) 1 large cubed chicken breast (the one I get is around 2lb)
2) can of small round potatoes - not necessary - I added these as my wife then gets a vegetarian option in the dish
3) 1/2 cup sour cream
4) Pack of 'Shan' Tandoori masala - from indian store - I make my own masala too but I like this one for color
5) paste from: 2 de-seeded chilis - I use jalapenos, 3 large garlic cloves, 1/2 tbsp ginger
6) 1 1/2 teasp chili powder
7) Garam masala - I make my own by using 5-6 cloves, 2 bay leaves, corriander seeds, cumin seeds, 2 teasp cinamon powder, 1/4 teasp nutmeg, 1 large brown cardamon or 1 teasp cardamon powder - I roast all these in a pan till corriander seeds are browned then i powder them in a mortar.
8) 1 14 Ounce can tomato sauce
9) 1 large yellow onion - finely diced - very finely
10) oil & ghee
11) sugar & salt

Process
1) I take the sour cream add equal amt of water and whisk together add 2 teasp of shan pack masala and set aside
2) 1 teasp garam masala to the tomato sauce in the can and set aside
3) To the chicken add some oil, thrown on some garam masala, shan masala, and marinate for 1/2 hr
4) Get potatoes out of can - rinse couple of times, then put them in a vege or chicken broth for 1/2 an hr - remove from broth and put same marinate as the chicken and set aside
5) While everything is marinating start sauteeing the onion till it's starting to brown
6) After onion is browned put it to side of pan add oil to center - after oil heats up add 1/2 the ginger, garlic, chili paste. When it smells add he chili powder and 1/2 the garam masala - let it brown in the hot oil and add the tomato sauce.
7) cover and cook for 20 min - adding some water or stock to the pan if needed
8) uncover blend with the onions which were off to the side of the pan - let cook for 5 more min
9) While the Tomatoe sauce was cooking in another pan add ghee and oil and sautee the chicken cubes - don't cook completely as they'll go in the gravy and cook through - just brown them and take them off heat.
10) Do same with potatoes
11) After step 8 tomatoes and onions have cooked - make space in center of pan add oil - let it heat add rest of garam masala, and ginger garlic chili paste - let it heat and brown the masala and add the chicken - stir everything together
12) slowly add potatoes
13) let everything simmer for 5 min with covered lid
14) Remove lid - add sour cream mixture - stir and cover lid and let cook for another 15-20 min - the oil will start to come to the top.
15) add 5 teasp of sugar and stir in, add 4 teasp salt - stir and cover and simmer for 5 min.
16) Taste great on day 1 but on day 3 it's fantastic!
17) Get some Naan from Trader joes and enjoy - you won't order Chicken Tikka Masala in a restaurant again!..
