This is my first attempt at doing a BIR version of a traditional Sri Lankan curry.
My inspirations were :-
Sri Lankan black lamb curry

https://curry-recipes.co.uk/curry/index.php/topic,5948.0.htmlBlade's chicken tikka
Precook 1/4 onion plus green chilli. I use large Morrocan ones because they're easily available and they don't disintegrate. I didn't bother adding any thing to this.
Heat oil: 1 1/2 pretentious chef spoons
Add GG paste. 1 tsp garlic, 1/2 tsp ginger
Add 1 star anise + 10 (ish) curry leaves.
Add 1 tsp tomato puree mixed with water
Add 1 tsp black curry powder (in the first link), 1/3 tsp tumeric, 1/3 tsp black mustard seeds, 1 heaped tsp chilli powder, 1 tsp black pepper (freshly ground)
Add ladle of base ( CT's I believe although it may have been JB's)
Add Chicken tikka, I use Blade's recipe as a base, but this was a little different. I used 750g of chicken, 1 tsp of black curry powder, 1 tsp tandoori masala, a 1/2 tsp of 'paprika', 1 tsp of GG paste, squeeze of lemon, a splash of veg oil and 1 blade of lemon grass (minced).
note:- I only used half the chicken in the recipe.
Add rest of base
Add 3cm piece of pandanus (ranpe)
Add 1 tsp cider vinegar
Add precooked onion and chilli
Cook til you happy with the sauce.
I'm sure I've made some mistakes, I've eaten nothing since a 'London' cheesecake for lunch, I'm sick which is why I'm at home and I've nearly finished my bottle of wine...

Anything not clear, just ask. I won't teach you to suck eggs on the basic method.
