Coffee and orange juice

In the Colonial era, Americans preferred tea. However, after England started to tax tea, Americans responded to the Boston Tea Party and drinking coffee became a patriotic duty.

In the 20th century, oranges were found to be an excellent source of vitamin C. In 1942, the U.S. Army offered money to the company that could invent frozen orange juice that tasted good. Richard Morse succeeded to manufacture frozen orange juice concentrate under Minute Made, making O.J. a popular morning drink.
