There is no Indian hand-held cake in Journey to the West because the author hasn't been there and doesn't know about Indian hand-held cakes.

1. Most of the foods described in Journey to the West are the delicacies in Jianghuai area of China, because the hometown of Wu Cheng'en, the author of this famous book, is Jianghuai area.

2. According to the relevant data, the most intuitive reason for the problem that there is no Indian hand-picked cake in Journey to the West should be that the author has no relevant knowledge reserve. There is no Indian hand-picked cake in Journey to the West because he has never been to the countries along the way to see the local customs, and of course he doesn't know Indian hand-picked cake.

3. The writers of Journey to the West mostly collect information from folk stories and the experience of Xuanzang's journey to the west, forming a general story framework of Journey to the West. Therefore, for a story with such a big background as Journey to the West, it is difficult to take care of some details.

5. As for why Journey to the West uses the cuisine of Jianghuai area, it is natural that Wu Cheng'en is more familiar with the food in his hometown and writes it more easily because there is no Indian hand-grabbed cake in Journey to the West. In this case, instead of writing unfamiliar exotic food, it is better to write your own familiar hometown food. So there is no Indian hand-grabbed cake in Journey to the West.
