Where did cream cheese and olive sandwich origin?

Cream cheese and olive sandwich is most likely to originate from the United Kingdom. It was first mentioned in a cookbook in 1858, and has been a popular snack and sandwich filling in the UK since then.

- Cream Cheese's origins can be traced back to Ancient Greece where they produced a fresh, soft, unripened cheese called 'Tymrous' with curds preserved in brine, which many say is the earliest form of cream cheese.

- The olive is one of the oldest known cultivated trees and is believed to have originated in the Mediterranean region. Olives have been used in various forms for thousands of years, including as a food, oil, and medicine.

It's possible that the combination of cream cheese and olives in a sandwich came about as a result of the availability and popularity of both ingredients in the UK. The briny flavor of the olives complements the creamy texture and slightly tangy flavor of the cream cheese, creating a savory and satisfying combination.
