Ambergris
You may have known that whale vomit has been a component of perfume for centuries, but did you know that in the 1700 and 1800s, it was a popular ingredient in many luxury dishes as well? It was used in beverages, served alongside eggs, or added to hot chocolate in not only America but also around the world.
Ambergris is actually very hard to find since it’s only produced by a small percentage of sperm whales. It forms on the ocean surface and floats, but will only rarely make landfall. Because of that, it’s been a very valuable substance for years.
