Oh, I like that idea ... the olives will certainly add a nice touch.
The black garbanzo beans have a richer, somewhat more earthy taste, at least the ones that I tried did. However, I bought the least expensive ones just to try, and there were two ther types/brands in the market. Both had a deeper color and the owner of the market suggested one of the choices other than the one wjich I bought. I'll try onee of the darker beans this next time.
If you go to this thread http://www.cheftalk.com/forums/recip...mus-humus.html
and scroll down you'll find a few comments about the black garbanzo beans and a recipe that shows them off very nicely.
My notes on the recipe:
Notes: Use two chipotles and a little more adobo sauce. Use agridulce paprika.
Rinse chipotle can and use the adobo/water mixture in place of plain water.
1 cup cilantro leaves could be OK
