Well Woks Up
It appears there aren't many things in this thread You do agree with

have you been drinkin with the Snowdog ?
I have stated in earlier threads that an old friend of mine (Bangladeshi) had his own establishment but He NEVER used Ginger Or Garlic Paste he Always used Fresh SO Your Wrong on that Count :

Garam Masalla OK I never seen him grind his own spices but that's gotta be up to the individual if You don't want to grind your own then Don't But there's No way on this earth will You or anyone else for that matter convince me that ready ground Garam Massala is better than freshly ground stuff

The case for keeping your spices in the cupboard for months well that's again up to the individual but 50p to 60p for a 100g bag isn't gonna break the bank is it ? you can then rest assured your not using SawDust after spending the time and effort trying to produce a dish using inferior products.
I'm sorry to say Woks Up but I think you'll be chasing that dream of finding that Golden Egg for a long time with your Ideas.
