Cornish pasties predate Spanish empanadas by a few hundred years. So it might be fair to say that empanadas and patties are Spanish and Jamaican versions of a cornish pasty. The patty is more likely to be a Jamaican take on the patty though tbf. The empanadas could have developed independently. They are all just meat and veg wrapped in pastry at the end of the day.

There is a shop that sells pattys all over london. Quite common tbh.

When I make crepes I don’t use salt or sugar. So I have a few savoury and then a few after with a sweet filling.
