So I don't do much cauliflower mash, but I can tell you from my pre-keto days, that water is the enemy of mashed potatoes. The technique that I always did, to avoid mealy/watery mashed potatoes, was to drain them well, and then put them back in the hot pan and just cook them alone to cook out moisture. This dries them out so that they can soak up all that butter. I don't know if the same technique would work for cauliflower, but it's worth a shot.

Otherwise, squeezing them through some paper towels or a cheesecloth might help.
