Cashew nuts, also known as kaju, are a popular type of nut known for their rich and creamy flavor. They are often consumed as a snack or used as an ingredient in various dishes and desserts. "Kaju baby bites" is not a commonly known term, so it might refer to a specific recipe or a particular product that I'm not familiar with. However, I can provide you with general information about cashew nuts and their culinary uses.

Cashew nuts are native to Brazil but are now widely cultivated in many tropical regions around the world. They are the seeds of the cashew tree, which is a member of the Anacardiaceae family. The nuts themselves are found attached to a fleshy, pear-shaped fruit known as the cashew apple.

Cashews are typically harvested once the cashew apple matures and falls to the ground. The nuts have a hard outer shell, which must be removed before consumption. The shells contain a toxic resin called anacardic acid, so they are carefully processed to remove the resin and ensure the nuts are safe to eat.
