Why is this the answer?

The answer is grapes because this clever riddle describes the life cycle and uses of this wonderful fruit. When the riddle says, "The sun bakes them," it is talking about how grapes need a lot of sunshine and warm weather to grow. The sun gives the grapes energy, helping them turn from small, hard green berries into big, juicy, and sweet bunches that are ready to eat. The warmth of the sun is essential for ripening them on the vine, almost like baking a cake. Then, the riddle moves on to "the hand breaks them." Once the grapes are ripe, people go into the vineyards to harvest them. They carefully use their hands to break the bunches off the vine. This picking is the first step of turning the fruit into a food or drink. The third clue is really old fashioned and says, "the foot treads on them." This is a historical clue. In many places, long ago, and sometimes even now, people would put the picked grapes into a large container. They would then step on them with their feet to crush them and squeeze out the juice. It was a fun way to get the sweet juice for drinking or making wine. The foot treading is a very important part of preparing the grapes. Finally, after the grapes are grown and processed, the last thing that happens is "the mouth tastes them." Whether you are eating a fresh, plump grape, enjoying a glass of purple grape juice, or tasting something else made from them, the final step is always enjoying the delicious flavor with your mouth. This neat puzzle uses all those descriptions to lead you right to the answer: grapes.
