Cranberries are an incredibly tart fruit, and cranberry sauce with sugar didn't become popular until the 19th century, and only became a Thanksgiving staple in the 20th century once bog-harvesting became the primary way to harvest.
Cranberries, alongside blueberries and concord grapes, are one of the few commercially growth fruits that are native to the United States. You can actually thank Ocean Spray for their innovation in harvesting cranberries that lead to the jellied can-shaped sauce on your table each November.
Indigenous folks were known to eat cranberries and to use them as a dye for clothing (so it's likely they could've been found at the Thanksgiving table in 1621), and the first recorded recipe of cranberry sauce does date to 1796, the popularity didn't really take off until they were able to be harvested commercially. Prior to bog-harvesting, cranberries were dry-harvested from vines, which was a difficult and arduous process. However, despite the more efficient bog-harvesting method, the process was also much more likely to damage the delicate berries making them too imperfect to sell. Thus, the canned jellied cranberry sauce was born.
