I’m not even a little Arab or Mediterranean, but I’ve made a ton of hummus for my vegan wife and our daughter who loves the stuff.

The biggest pitfall I’ve seen with home-made hummus is that most people make it too lumpy. I’ve apocryphally told people that it’s an insult of the highest order in the Arab world to tell someone that their mother makes lumpy hummus.
In any event, the problem is people either use a crappy blender (I recommend a full sized food processor) or they don’t add enough liquid in the form of agua faba, water, lemon juice, etc. to let the mixture really puree until smooth.

My recipe doesn’t look much like this one (aside from the ingredients) but I always make sure to add more liquid at the end until the hummus is very smooth with not a speck of lumps or grittiness.
