Cauliflower Tahini Soup with Pomegranate Herb Pesto

My recipe for ‘Cauliflower Tahini Soup with Pomegranate Herb Pesto Soup’ was influenced by a recent dinner at Jean-Georges’ abcV. Their whole roasted cauliflower with tahini sauce, pistachios, and herbs was out of this world.  One of the most enjoyable vegetable dishes I have had was easily translated into a soup. 

During these colder months, soup is a great way to maximize your vegetable intake. Using a high-speed blender, you can create a perfect velvety and creamy soup without any added dairy or nut milks. You will be surprised how creamy this soup is with just cauliflower and a sweet potato.

Like many of my recipes, this one is inspired by what is in season. Right now and until February, you can find fresh pomegranates at the supermarket. There is something magical about cracking open a pomegranate and exposing it’s beautiful ruby seeds. The less magical part is the mess you makes when picking out the seeds. Here is a great method for removing the seeds. Or be fancy and pay double to get a small container of seeds.

Colder months also bring a wide variety of potatoes in different shapes, sizes, and colours.  In this recipe I used a white sweet potato because I wanted the soup to be white in colour.   If you have trouble finding one feel free to use an orange sweet potato.
