The Goldfinger banana is one of our most rapidly producing bananas in the USA. It has a nice flavor and makes a great addition to smoothies.
Fresh Goldfinger as mentioned peak flavor is at about 1-3 days after the finger has turned solid yellow. You should see a few dark spots on it, and it should be slightly darker yellow. At this stage, it's sweeter than a cavendish and has a wonderful, tangy background flavor.
