i always add a bit of water the bean were cooked in.. or more lemon juice.. the ready made canned hummas is at times to soft and liquid for my taste.. (its as soft as yogurt) i like hummas some what thick-- (like soft mashed potatoes--stiff enough to almost keep its shape--but soft and creamy in the mouth.

try warming the tahini before mixing it in.. (set the jar or can in a warm bowl of water..and stir well) you can also add a bit of sesame oil to make it 'creamier'--softer and richer tasting at the same time-which defeats the purpose of eating hummas, and turns it from a not to high calorie vegetable dish into a calorie laden 'vegetable pate'!
