I don’t know about “better”, but I’ve been experimenting with adding bitter chocolate to my indian curries. The thinking being, some masalas are a bit like mole if you squint (yes, I know most moles don’t actually contain chocolate). Balancing out the bittersweetness has been challenging, especially given that the tomatoes I can get around here are already quite sweet. It also affects how much lemon juice or amchoor is needed. I’m not quite convinced yet that it’s a good idea lol.
