Vindaloo, the Indian dish, comes from the port city of Goa, where Portuguese traders introduced the locals to a stewed pork dish with wine (vinha) and garlic (alho), named “meat with wine and garlic,” or “carne de vinha d’alhos.” Eventually the wine became replaced with vinegar, and taboos elsewhere in India against pork eventually caused the dish to branch out to all sorts of different meats.

Butter can also be white based on the milk/cream it is made from. My shop buys a lot of farm fresh milk for ice cream. We use some of the cream to make butter. for a while, it was completely white because the cows only got hay but we recently had good rain and now that they got fresh grass the butter is yellow.
