Cruising in the tropics you will find bananas almost everywhere - slightly over-ripe ones (best for this recipe) are a dime a dozen. Banana Bread was an absolute favourite on our boat AND easy to make. When we baked we normally made two or three loaves at a time as they stay "fresh" for a long time - that is if my wife could keep me away from them.
