Place a large saucepan over medium heat. Add brown butter, shallots and garlic cloves in the pan and saute for about 1 minute until fragrant. Add cauliflower florets, broth, truffle salt and fresh thyme to the pot, cover and let cook for 15-20 minutes, or until cauliflower is super fork tender.
While cauliflower cooks, add bacon to a medium saute pan over medium heat and cook on both side until crispy. Set aside then cut into small pieces. In that same pan, remove all but 1 teaspoon of bacon fat and add 1 teaspoon of brown butter. Once very warm, add sage leaves and cook on both sides for less than 1 minute, until sage is crispy.
Once cauliflower is done cooking, remove thyme sprig then add garlic powder and sea salt. Use an immersion blender to blender cauliflower soup until completely smooth.
Pour cauliflower soup into bowl, then top with just a little truffle oil, bacon, crispy sage leaf, pomegranate seeds, and a bit of black pepper.
