I just made my first (successful) batch and it’s ok, but it doesn’t really taste like store bought at all. And the goal is to get a similar end result since that can be used get other people into making their own instead of buying it since it’s marked up so much.
The trick is too much tahini and too much garlic. Also beans can take a lot more oil than a lots of carnists would think, so maybe you just need more EVOO. I make a huge batch every week and I've got hella good at it, way better than most stores except for this one Greek deli that has fucked up hummus. Practice definitely helps.
But yeah a lot of mayo recipes online are like hella skimpy on the tahini but tahini is the backbone of hummus.
Oh also freezing the water before you add it is like a generally recommended trick
