Been thinking about this
I would love to get the flavour I'm after
I had pretty much given up, but this sort of set me off again
I think the fenugreek seed powder is right
The onion powder certainly does no harm and it does have a fried onion aroma
I don't think it needs tomato puree, it's too strong a flavour
I think blended canned tomatoes is closer
garlic ginger is right too
maybe not the garlic powder
I reckon that the base needs to be different
I think a very simple base made with Onion garlic ginger but also chicken bones/scraps and not overspiced
Maybe bayleaf and cardomon
There's got be someone who knows
This is just so frustrating
About five years ago I was in a takeaway kitchen and allowed to cook my own curry using an old style base.
Absolutely nothing clever about cooking the curry
None of this "pre heat the pan, get the oil really hot, don't burn the garlic, fry out the spices" milarky
All you did was heat the curry gravy, add a little salt, chilli powder and pre cooked main ingredients.
The curry I cooked was a perfect madras
Maybe a pinch of fenugreek leaves or garam masala went into other curries I saw prepared
A couple had a prefried garlic paste
Some had some deep fried onion and peppers added
A few had cream, coconut powder, sugar, red masala paste added
But it's REALLY simple stuff when you've got this base
I was lucky enough to see the base prepared and it's so simple except for one ingredient
This flavoured oil
Basically the gravy is loads of onions & a small can of tomatoes boiled with salt and turmeric
After one a half hours, add curry powder and about two litres of strained old oil
Straining takes out all the burnt bits and impurities left behind
As soon as this oil goes in the gravy, the BIR aroma magically appears
You know that smell when you open a carton of curry
Or the smell on the carrier bag which has got about three curries in
Well it's that, except much bigger because there is so much in the pot
I've even tasted this oil on it's own
It was kept in a fridge
It's slightly hot, and has a used slightly spicy flavour
It's not as runny as fresh oil and the base of the container seems to be almost setting (maybe ghee or fat?)
I don't know if it's just from cooking bhajees or chicken or what
But I got quite obsessed with trying to duplicate it
and I failed
I cook some really great curries
But I want to cook the best
And old style BIR are the best
