Interesting. A couple decades ago, I made my own hummus for as long as it took to use up the rather large jar of tahini that I’d bought. Afterwards, I never did it again - too much bother. Now I just buy a family size tub at BJs Wholesale Club each month when we make our supply run there.
BTW, hummus and avocado mix beautifully together - I forget if we discussed that! And now you say that hummus freezes well. Maybe that would be a better way to freeze my avocados (just thinking out loud here).
I put the hummus on top of my cut-up avocado and it’s great! I make a salad of baby spinach, cut avocado, hummus, and some lite Italian dressing. Using a food processor makes the hummus making process much easier.
