[Answer] Who produced and canned the first jellied cranberry sauce in 1941?

Step 1 : Introduction to the question "Who produced and canned the first jellied cranberry sauce in 1941?"

...Marcus L. Urann was a lawyer by trade but he left the legal profession early in the 20th century to buy a cranberry bog. Cranberries are only harvested between mid-September and mid-November, making them available fresh for only about two months. Urann wanted to devise a way to make them available year-round. Canning them offered the solution to the problem. The man who gave us the Thanksgiving staple that keeps the shape of the can it came from died in 1963. Source: SmithsonianMag.com

[Ans] What identifies a cranberry as ripe?

Step 1 : Introduction to the question "What identifies a cranberry as ripe?"

People used to call cranberries "bounceberries" because they bounce when they're ripe. Some called them "crane-berries" because the blossoms on the plants resembled sand hill cranes. Over time, the name shortened to just "cranberries." Along with blueberries and Concord grapes, cranberries are North America's only true native fruits. Cranberry vines are hearty, many producing fruit for up to 150 years. The tart berries straight from the vine are too much for any except wild bears. Once the berries are bouncing, however, people are more than happy to make them into jams, jellies and other tasty treats. Source: FoodSiteMagazine.com
