How long should frozen berries be boiled?

How long should frozen fruit be boiled? Only until it thaws or up to ten minutes? This refers to raspberries, strawberries, and blueberries.
You do not need to boil frozen fruit. Frozen fruit is best when thawed slightly. The thawed fruit can be eaten as is or added to other recipes, cooked or uncooked. Strawberries, raspberries, and blueberries should be cleaned, rinsed and dried before freezing. Fruit is high in acid and is unlikely to cause food poisoning.
