Steam the cauliflower in a steamer insert set over boiling water, covered, until it is very soft, 15 to 20 minutes. Transfer the steamed cauliflower to a blender
and puree with the cheese, milk, sour cream and lime juice until smooth, scraping down the sides of the blender jar as necessary. Add the adobo sauce
and salt and pepper to taste, pulse
a couple more times and transfer to a serving bowl. Sprinkle with cilantro and serve.
