My mission began around 20 years ago with trying to replicate my children's favourite "Indian" dish, being Mango Chicken. Most Indian restaurants and takeaways here cook it and while there are some minor differences between establishments, it is fairly safe to say that it is always very similar. I did finally achieve a dish that is nice to eat and close to the mark thanks to the advice of Chewytikka,

I nearly turned my kids off it with all the near misses and "try this one" attempts. I took a couple of years off regularly cooking curry for various reasons but I'm about to give it another try. Yesterday I began on a different path, using the Restaurant-Style Curries pages from the newly rediscovered Wayback Machine captures of the Celtnet.org.uk. (A big thankyou to PP here. I thought it was gone forever.)
I made a batch of the sites Base Gravy (Restaurant Curry Sauce) and then used it to precook some chicken (Indian Cooked Chicken). I made a Chicken Korma using the sites recipe and the Korma Curry Powder as well which was delicious. I also did the sites Lamb Rogan Josh and Naan plus my own mixed vegetable curry.
All very nice but the interesting point is that the pre-cooked chicken, when tasted on its own, is strikingly similar to the flavours I've been trying to achieve. I might be onto something here. I guess I'm off the the Indian grocery shop for yet another tin of Mango Pulp and some fresh almond meal.
