Yes, you can. Traditionally, hummus is made by removing every individual chickpea’s skin. Though it involves the time to remove the skin, the outcome is worth trying.  Put another way, if you prefer the texture quality, you remove the skin.  If you prefer to keep the recipe simple, you may blend the chickpea with its skin. The texture may be a little coarse when compared with the store-bought. But the deliciousness remains the same.
