Play Sleuth JS.
I'm sure lots of you out there remember the excellent DOS game Sleuth, which was written by Eric N. Miller in the 1980s. I absolutely loved it, and still play it at Christmas with the family. Unfortunately, it requires an emulator to run nowadays, which can be a bit fiddly.
Yes, I think it's a lamb thing, and you use the chillis for flavour, colour and heat. Vinegar-based curry? That, errr, doesn't entirely sound appealing. Though vindaloo is usually a vinegar thing IIRC.
