The Indian curry vindaloo originally contains which meat?

Vindaloo is an Indian curry dish popular in the region of Goa, the surrounding Konkan, and many other parts of India. It is known globally in its British Indian form as a staple of curry house and Indian restaurant menus, often regarded as a fiery, spicy dish, even though it may not necessarily be the spiciest dish available.

Restaurants in Goa offering traditional Goan cuisine serve vindaloo with pork, which is the original recipe. The dish was popularized by Goan cooks (whom the British favoured, because they had no issues in kitchens and bars when handling beef, goat meat, pork, or liquor) in the British establishments and the ocean-going liners. Restaurants outside Goa serve vindaloo with chicken or lamb, which is sometimes mixed with cubed potatoes.
