It literally translates to "pea flour," as gram flour is commonly made from chickpeas, which are part of the legume family and are closely related to peas.
However, you might also encounter other terms like:
* "harina ng butil ng gisantes" (pea seed flour)
* "harina ng chicharon" (chicharon flour) - This is a more colloquial term that refers to gram flour used for making savory snacks like chicharon.
It's important to note that the term "harina ng gisantes" is not as widely used as "besan" in some Filipino communities, especially those with a strong Indian influence. "Besan" is the Hindi word for gram flour, and it's often used in Filipino cuisine.
