To make dried banana chips, you need bananas, water, salt and lemon juice. Use slightly unripe bananas for the best results. Some recipes may also feature sugar or syrup to create a sweeter variety.
Begin by slicing the bananas into thin 1/8-inch slices. Set these aside and mix the lemon juice with a small amount of water to dilute the sour flavor. Add sugar if you are looking for a sweeter flavor. When the mixture is homogeneous, brush the bananas with the mixture and then sprinkle salt over the surfaces on one side. Get a cooking sheet and spread the banana slices out on top of it individually.
Heat the oven to 250 degrees Fahrenheit and place the cooking sheet in for about one and a half to two hours. Halfway through the cooking process, flip the banana slices over to let the undersides cook. Cook them to the desired level of crispness and let them cool; the longer you cool them, the crispier they get.
For a sweeter version of this recipe, use overripe bananas and sprinkle them with cinnamon instead of salt. Repeat all of the other steps and let the bananas cool a little longer after done.
