The smell we get when pasing by our favourite restaurants in the afternoon when they're most probably cooking their base gravy, may almost certainly NOT be the smell we THINK our base gravy SHOULD END UP SMELLING AND TASTING OF. !!!
REASON: The extracting ducting from my kitchen to the garden is coated in "OLD OILS etc"'.
This gives out a combined smell of "The base gravy; Whole spices; Garam Masala and largely from general cooking of the restaurant/takeaway dishes" which is I've discovered is "THE BIR SMELL" which we all love and want to replicate?
Realising this, I proceeded with many experiments which I've got good results:
All you need to do to prove this is; cook your normal base gravy, smell the extractor exhaust outside. IT WONT BE GOOD! Then cook your normal curry. Again, smell the exhaust but it probably won't be quite right! Then in oil cook some Garam Masala whole spices; Ie. A little Cinammon, Cloves, Green Cardamon, Star Anise & Mace. Then give it a day or two, turn the extractor on, pop outside and smell what comes out and I guarantee you'll be amazed !!!!!!!!!!!!
It's BIR... Not only the smell is BIR but also the taste of your curries.
I'll report more when I have time
