As I said, I think store bought is fine but if my first introduction to hummus was store bought, I don't know if I would've ever eaten it again. I don't know why, the taste doesn't go well with me and I've tried many brands. But overall, I'm obsessed with hummus
Oh and I've heard if you have a regular blender, you can use a mason jar with it, although I haven't tried it. I have a magic bullet blender which I use for things like smoothies and hummus.
