In fact, there is only one kind of jicama, not two. If you see the description of "two kinds of jatamas" on some platforms, it may be based on the different preparation materials or practices.

Ma yam is an elastic and sticky traditional food made from glutinous rice flour or other starches. It is also called mochi in some places. It can be made in a variety of ways by adding different ingredients and flavors, such as adding red beans, black sesame seeds and peanuts.

So, some places may distinguish between different ways of making jicama or ingredients, but this is not to say that there are several kinds of jicama itself. Overall, there is only one kind of jicama, but it can be distinguished according to different practices and flavors.
