A very good question.There is still is a distinctive smell I get when I walk past a certain restaurant close to where I
live.It literally wafts through the streets and is wonderful.Having said that,my favourite restaurant,also close by doesn't have the same smell neither does my local takeaway kitchen that I regularly visit.They all produce top notch food so I really don't know why they produce 'that' smell.They're always very busy with punters so maybe it's just a case of the sheer number of curries they are cooking.
As discussed on here before, cooking yourself or being in a takeaway kitchen can really play tricks on your senses.If I cook a curry feast at home after a time I can detect very little aroma or any of that 'BIR' smell,yet if I return to the house later the my whole home smells like a curry house,it literally lingers for days.Imagine a busy curry house cooking like this every day and that's probably where that magic smell comes from.
I think my curries are as good as they're going to get now,I get takeaways sometimes and think I can do so much better.Having said that,I still go to some places and think 'wow' that is superb.All down to the chef,no mystery ingredient or nonsense like that,if there was such a thing I would have seen my chef use it over the past few years I've been in his kitchen.Back in 2010 I was still quite a novice at curry cooking.I brought all of the ebooks etc but there was still something missing,and that was technique and actually how to cook curries properly,none of the books went into this.The best thing for me was actually getting into a kitchen and watching how a proper chef cooks,better than all of the books put together.Not stiring the pan, literally burning the garlic in the initial fry(this is one thing all of the ebooks tell you not to do),all these things come together in a BIR kitchen to produce that distinctive taste and aroma
