In a comparison taste test of all supermarkets indian food done by a newspaper or chef or something a few years ago, Asda Indian food came out best by quite a long way.
It's the only supermarket Indian food I buy, I think it's really nice.
Given Gollob - but when I go to France where there are no Indian takeaways for 100's of miles I always go laden down with Tesco tinned curries which are acceptable, especially the lamb rogan josh and the chicken tikka masala.
At the end of the day it won't be inedible will it. Throw some alcohol down your necks beforehand and I bet all the food will be devoured before you can shout 'salmonella'.
