until it tastes right. you cant google and trust a million hits that say how much lemon, you have to learn to cook w/ your nose and eyes and ears and taste buds. if you're not adventurous per se and dont eat a load of foreign cuisine, it will take practice. go to a real middle eastern couple of places and eat theirs and get fam w/ what really should taste like, after that is personal taste. I will say this, if you want 'real' flavours, stay true, and do not omit XYZ because 'I dont like chickpeas' or I'm not really into garlic' etc. MAIN items in REAL hummus: chickpeas, tahini, lemon juice, olive oil, garlic (fresh), salt. and after that you can add mint and or cilantro and cumin is pretty common ingredient also. Anything else is no longer actual hummus. but if you add other things dont pretend its pure real authentic, and dont believe anyone who says it is.
