Every night at dinner, I tapped out a bit of hummus powder into a bowl smaller than a cereal bowl. I added a splash of olive oil from the cruet by the stove, and stirred while moving the bowl in and away from a running trickle of tapwater. I stirred until it was slightly runny, turned off the water. Stirred more as it continued to thicken, and sat down using the same spoon to serve it to our child for dinner.
But fluffing a lot of powder about was less appealing than I imagined. We more routinely bought boxes of hummus, that contained the powdered goodness in smaller less likely to effervesce packages. I don't recall taking Hummus out with us anywhere except a friend's house, though this we did often.
Our child ate so much Hummus, so much, that when we were not at home and it was time to eat - I stepped into a coffeeshop and bought a banana, just for the variety. I ended up carrying bananas in my purse not hummus powder. As a bonus the banana was something we could both eat and share. Hummus, for my taste, needs something, basil, lemon, and a variety of olives to be really good on pita or toast. And I never have toast points in my purse.
