tl;dr: Made one of the best curries today!Ok, so my girlfriend was studying with a friend when I arrived from work and that seemed like the perfect excuse to make a curry for all of us (not like I need any excuses, but to add some storyteller seasoning to the story) - I precooked a bunch of breasts using viceroy's method with a slight twist: I've added lemon to the chicken to help tenderize it. I don't know whether this makes the difference with the viceroy's method to precook chicken, but it's a practice I've developed from long ago, as soon as I buy some chicken, I slice the breasts (I only eat breast), rinse and then squeeze half a lemon (depending on quantity) on top and let it sit until needed. Anyways, last time this friend was around, I offered to make a curry, a chicken korma, but as I didn't have space to precook chicken on the stove top, I followed a method that chewy recommended, to precook the chicken using olive oil in the oven. I just didn't realize immediately that he meant it when using a whole chicken, in which case I would expect to have made a difference because of the chicken fats and what not and so my oven-precooked-chicken had a huge bite (i.e rubbery) to it and olive flavor, which tainted the chicken korma I made then. I had to eat it myself and regretted it. My girlfriend's friend offered some praise on the food, but I think she was being kind. My girlfriend who isn't very picky agreed then that it wasn't the best korma she's ever had from the ones made I made so far. So today I asked her friend what the curries she used to have when she lived in UK, she said "I can't think of the names, other than korma.." so I asked, what heat level she liked and she said 3/10 and I asked whether she'd go for a bhuna, dhansak, dopiaza..etc in the hopes to find out what she used to get, she said "Uh, I can't think of the names, sorry. It was back in 86-89!" that told me 2 things, she doesn't eat a lot of indian, but that she had (judging from what I hear around this forum, not from personal experience) experienced the best time of BIR food and as such, impressing her would probably be quite hard.

As she couldn't tell me a dish name I said, I'm going cook a chicken ceylon, seeing as she likes her kormas and enjoys a bit of heat. I used stephen lindsay's fail-proof recipe, with a few small changes, namely:
1. Used ktc pure coconut oil instead of my standard veg oil, which I've ran out of while pre-cooking.
2. Used SnS Saffron' base
3. I fried some onion.
4. I used 1/2 tbsp of deggi mirch (MDH)
5. I used 1 tsp of east-end mild madras curry powder (my rahah tin ran out and I just bought this one) and 1 tsp of BE, which is my current mix spice.
6. I watered town my tom puree further and my base a little, which meant longer reduction time.
The resultant curry was mild/medium-heat, with a mild coconut and madras-esque BIR curry smell with a bit of a tangyness from the lemon, but everything in the right balance, that kinda balance that our favorite takeaways seem to nail nearly every time. If only I had added less coconut, it would taste like my favorite bhuna! On top of that, my girlfriend still had 2 portions from yesterday's korma (or 1 portion if you eat like me) and my girlfriend ran across to our local takeaway and picked up 2 peshawari naans and pilau rice.
The reaction when she started eating (she didn't wait for me or my girlfriend to be ready to eat) was "Wow", she said "This is the best curry I've ever had in Ireland, potentially one of the best I've ever had." and I could tell by the way she was eating how satisfied she was and the praise didn't stop there. She had some of yesterdays korma and she asked me if my girlfriend had bought it in the takeaway just now as by her standards it was just perfect.

For me, it was without a doubt my best curry yet and I judge myself very very heavily. I can say that, if I understand what worked right today and be able to make it repeatable, it may very well move my cooking to my end goal or close enough. I'm quite confident that the point 5 and 6 contributed highly, but viceroy's precooking method is a big winner too. The texture always comes out phenomenal and on that note, I would like to thank every single one of you for the endless amounts of help/advice and motivation as well as recipes.

cheers!
