Curry was originally invented by British sailors to cover up the smell of food. People often think of curry as an Indian delicacy, but in fact this dish does not exist in India. In traditional Indian restaurants, there is only "masala" on the menu, not "curry".
At the beginning of the 18th century, British colonists invented curry powder by mixing various tropical spices together based on "masala". Because its cooking is simple (just cut various meats and vegetables into cubes and cook them with curry powder), the ingredients are not fresh and it is difficult to eat, curry is very popular among sailors who have been drifting at sea all year round. Later, curry slowly became popular in the UK and became the second most popular national delicacy in the UK after fish and chips.
