There is more to sugar than just sweetness. Sugar also intensifies the taste of fruit and vegetables and is used as a preservative in jams and other foodstuffs. And thanks to the sugar in it, ice cream is nice and soft. The more sugar that is added to the ice cream, the slower it freezes and the softer it becomes. Ice cream is not the only product to benefit from sugar; chocolate melts in the mouth thanks to sugar. Sugar also quickly and easily absorbs moisture. A bit of sugar in the biscuit tin keeps biscuits fresh for longer. And a spoonful of sugar extends the vase life of cut flowers. The flowers use the sugar to grow.
