I am at a loss to understand why anyone would use Patak's paste in " abundance " in order to re-create BIR style curries . You may as well call it Patak curry . These generic pastes tend to taste all the same and mask the authentic flavor that we are trying to achieve .
I realize that we have visited this topic before , but I would be very concerned about storage and cross-contamination when reclaiming and using oils from multiple sources - just a thought .
