I watched a chef yesterday cook a vindaloo (the best i have ever tasted,yes the best and favourite)
In the technique ,the things that STOOD out for me, compared to the general standard way, was;
Adding a knob of butter.
And initialy at the beginning, adding about half chef spoon of ,what i can describe as ,an onion mixture (which when quizzed,) suggested it had garlic ,ginger and spices .
that i am investigating now.
It wasnt quite a paste ,as i could still see that there were chopped onions in it,the colour had a kind of tumeric /tomato colour to it .
also to make it clear these were in ADDITION to the usual ingredients, ie. curry base,chilli powder,coriander, tomato paste and lemon juice.
may sound like a daft question ,but,is this post about something like what im describing?
