What is applesauce?
Applesauce is a simple sauce made of cooked or baked apples. Peeled or unpeeled apples are used to make the sauce that can be spiced or sweetened.
The recipe for banana coconut cake calls for unsweetened applesauce. You can buy it at a grocery store or make the applesauce at home.
Banana coconut combination
Coconut, especially its dried form, has a unique flavor that describes the flavors of other food.
Coconut taste opens up by combining it with other food as well. One of the tasteful food combinations - coconut banana combo - is based on a sweet and nutty flavor that coconut gives to tropical bananas.
