I was skeptical, but mashed "potatoes" with cauliflower
? Really effing good. Though I might have overdone the garlic, heh. I used homemade ghee
(which I'd never made before) instead of butter, and it's tasty and unctuous and just good. Definitely not potatoes, but creamy and good in its own right.
(Also, do not think that you will be able to get this stuff creamy by hand. Haul out the blender or food processor.)
