"I love cauliflower, but wanted to make something different and decided to make soup! This is a great Paleo recipe and Italian recipe to enjoy. I may add red pepper flakes next time to give it a little extra kick but the white truffle oil did make cauliflower soup really amazing. I use my emulsifier to blend right in my pan. I don't like to dirty another appliance if I don't have to. This is much easier to clean then a blender! Just remember to remove from heat and set emulsifier in the pan and set to the on position! White truffle oil is available at Italian markets, many specialty foods stores, and select supermarkets."
