That's a lovely food vlog!!
Yes, curry crab is definitely something Caribbean.
I think Trinidad and Guyana use the most curry in different dishes due to the strong Indian influence, but most Caribbean countries have curry crab. Also roti, and doubles might not be fully mainstream, but are also slowly becoming more popular.
Thanks mate! True, I was amazed to see alot of Trini street foods abroad and getting some mentions in US TV shows 😳
Yes, your fellow countryman are working really hard to get Trinidad known around the Caribbean and in the US as well 😊
