Vindaloo
The fiery Goan original: a vinegar-and-garlic-marinated meat (traditionally pork, adapted in BIR menus to chicken or lamb) simmered in a dark masala loaded with red chillies, cumin and mustard seeds. The sharp acidity from vinegar plus aggressive chilli is the signature; potatoes are a BIR addition (the "aloo" suggestion) but not part of the Portuguese-origin dish.
