In buying watermelon, it is usual to ask the vendor repeatedly whether the fruit is sweet or not. Obviously, no vendor will say that his commodities taste blunt. He is very willing to give a slice for free taste just to convince you to buy. Then he will ask you to select the fruit of your choice. Next, he will cut a triangular portion of it to show that it is really red. We have a perception that most red watermelon are sweet, hmm.. not always.
One day, I got an opportunity to have a conversation with the head chef of a hotel. Its was a coincidence that he was preparing watermelon for their visitors. I asked him what if the watermelon was not sweet. The customers will get disappointed for sure. The chef replied: That was easy. We sprinkle some sugar to make it sweeter. Customers will never notice that the fruit was added with some sugar. Sugar crystals will melt in few minutes after sprinkling.
The idea is very simple but I never thought of it before.
The same is true when buying corn. Some corn are sweet and some corn are not sweet. When making boiled corn, some sugar can be added to boiling water to make it sweeter and yummier.
