Just a bit of an update for you.
For those of you who have read my previous posts, you'll know I use SnS's base for this curry but when making the base, I omit the chilli powder and substitute the madras powder for mild curry powder. The resulting CTM is indeed AWESOME.
Now the update. In a restaurant not far from me, they do a curry I've never seen other than in there called a Chicken Tikka Masala Madras. Now it is exactly as it sounds and is actually VERY tasty and an exciting variation for those of you who like their curries spicy.
For this I use SnS's base as it should be (omitting nothing and even replacing Chilli Powder with Deggi Mirch) and when making the CTM paste using the spices, add 1 tsp of Deggi Mirch (or more if you prefer it hotter) to the mix. Then cook as per CA's recipe.
It worked for me, voila.. a chicken tikka masala madras!
