Hi Romain!
I turned to cooking BIR at home because Birmingham, Alabama is a bit far from Edinburgh! When I was back in the UK last month for a family visit I tried the local curry house option. I was not impressed. The basic tarka dal recipe here is fantastic, theirs was bland. The lamb pasanda recipe here looks interesting, theirs was a sweet, cloying mess. Basically, as I said at the start of this thread, the recipes here are legit and reliable and always produce a good curry - which is more than can be said about too many curry houses in the UK.
