Sweet and spicy foods are two completely different types of tastes. Sweet food has the flavor of sugar. Sugar is what makes sweet food sweet. In contrast, spicy food has little to no sugar and if it does then it can not be detected. As its name suggests, spicy food usually has a mixture of spices. When you eat sweet foods you stimulate your taste buds in a different way then when you eat spicy foods. Sweet foods such as chocolate or cake taste sugary and smooth. It is, no pun intended and for the lack of a better word, a sweet taste. In contrast spicy foods can create that sense where you are dying for water. Spicy foods are the ones that leave you sucking in air to rid yourself of the strangely addicting burn in your mouth. Spicy foods are the ones that leave your tongue tingling. When you compare a lollipop to a jalapeno the difference is pretty clear. One is a ball of sugar and one is a mouth full of hot. The same thing applies to a pie and Spicy gumbo. The pie satisfies the sweet tooth while the spicy gumbo satisfies your need for "pop". Sweet foods are more delicate in taste while spicy food have an added "bam" to it. In both cases, sweet and spicy foods satisfy the hunger of many people and when combined, at times, can create a beautiful neutral dish.
