Who invented ketchup?

Everyone knows that ketchup is a national treasure in the United States. However, the invention of ketchup is far from an American achievement.
Back in the early 18th century, English sailors brought “ketchup”—as it was then called—from the Malay Archipelago. This was a Chinese spicy sauce made from salted fish, shellfish, and spices. In 1792, English chef Richard Briggs replaced the fish component in the sauce with tomatoes. And that’s how it all began…
Meanwhile, the Germans, as is their custom, like to get creative. For instance, they prepare a fish sauce by mixing two tablespoons of ketchup with mayonnaise, adding Tabasco sauce, cognac, and whipped cream. Those who have tasted it say it’s a true masterpiece. Only the French, whose cuisine is considered the gold standard of culinary art, regard ketchup with the utmost disdain.
