Can a masticating juicer make good hummus?
In the meantime, I do have a masticating fruit juicer, and I am quite happy with the results it produces, including hummus. The skins of the chickpeas are somewhat a problem, but either peeling them or cooking with a pinch of soda in the pressure cooker is sufficient to get a very creamy hummus.
I still use the food processor for small portions, because the masticating juicer is a PITA to build up and then clean, but making large batches of thick hummus and freezing them turned out to be a good strategy. I also have to note that I make the hummus much thicker than standard, a bit claylike, and either eat it as-is (because I sometimes enjoy the texture that way) or mix it with more oil or liquid after it has thawed, saving space in the freezer. And the juicer works much better for this thick hummus than the food processor, which has trouble moving the substance around at that viscosity. For that, and for the general quality of hummus overall, I am very glad I got the juicer.
