I spoke to a chef and he actually wrote down the recipe.
He is a really nice man and I am sure that what he gave me is accurate.
There is no deception.
My only misgiving is that it seems very familiar.
I believe him, when he says, there are no other ingredients in the restaurant gravy pot.
I don't think there is a conspiracy to hide anything.
So, here it is:-
Stage 1:-
1 lb onion
1 tablespoon garlic/ginger puree
5% tomato puree (I assume he meant that as a percentage of the? overall amount)
He said use pureed tinned tomatoes or paste.
Both were ok.
1 small green pepper
2 teaspoon salt
Water (you'll have to guess the amount)
Boil the above for at least an hour and then puree
Stage 2:-
Spices? 2 teaspoon mix spice
This is Curry powder,Paprika,Turmeric,Cummin,Coriander in equal proportions
Salt as required
1 teaspoon chilli powder
1 teaspoon dried fenugreek
1 teaspoon balti paste
Also:-
1 tablespoon garlic/ginger puree
3 teaspoon oil
Add the spices to the pureed onion mix
Heat the oil and fry the garlic ginger until brown
Then pour in the onion mix (watch out for spluttering)
Cook for at least ten minutes and it?s ready
I think it might be an idea to use vegetable ghee instead of oil
(ghee from an asian shop)
He also said that his vegetables are boiled in simply water.
No spices.
I would also add that his curries are some of the best, I have ever tasted
If the gravy doesn't work, then it MUST be down to scale.
Try it again with ten times the ingredients!
Right then....someone else get a recipe to compare.
I bet it will be just like this, or like the thin yellow gravy from Bengali Cuisine
