In India, there are over 1000 varieties of mangoes. The fruit is used for everything from drinks to cooking – and it is pickled, stewed, juiced and even used for medicinal purposes. What you may not know about Indian mangoes is that until 2007 there had been an 18 year ban on importing them into the United States due to the pesticides used in India. Now that the ban has been lifted, there are approximately 20 types of "commercially viable" mango varieties that are exported from India to the US and demand for them is high.
What is most interesting about mangoes, however, is that there are hundreds more varieties of mangoes that you will never be able to taste outside of India. Most of these mangoes are too far from any shore of of the subcontinent to be transported before they ripen and start to rot. In other words, these mangoes are landlocked. Yet they offer one of the most authentic food experiences you can have in the world. The mystery and appeal of traveling to sample those mangoes is a draw in itself (admit it, even reading this far you are wondering how they might taste) – but few Indian tourism groups promote the experience or even offer it to travelers. In India, landlocked mangoes represent a missed opportunity.
Now think about your own business and what is "landlocked" in your experience. This might be the unintended uses for your product that people are embracing but you don't promote. Or the "behind the scenes" tour of your offices or production facility. Or the varieties of your product or service you decide not to release, but which still may have an audience. These are the secrets you are intentionally keeping because they are not convenient to market or go overlooked. They are a missed opportunity, but they don't have to be. It is the undiscovered parts of an experience that sometimes offer the best marketing opportunities … if you can just focus on spotting them.
