Pressure Cooker Sweet Potato & Leek Soup

Pressure-Cooker-Yam-Leek-Soup-Final-Small

With the temperatures dipping lower than they have in some time, all thoughts turn to soup. (I know what you’re thinking, “Wimpy Californians, can’t handle 40-degree weather”, and I’ll be the first to admit that you’re right. But in our defense, most of us don’t own trousers that go all the way to our ankles, much less shoes that don’t flip and/or flop. Let’s not even get into jackets.)

Yam-Soup-Ingredients-Final-Small
Anyway, I planned on making potato-leek soup, which soon morphed into sweet potato-leek soup. So I went to the store and bought all the necessary ingredients in the morning, so I wouldn’t need to go to the store later, after my Friday afternoon visit to the local pub (Friday is my day off of work, so a pub visit has become my Friday ritual).

Thick-Bacon-Final-Small

After getting home from shopping, I sat down to relax and peruse the blogs I usually read. Fortuitously, Mike Vrobel, author of Dad Cooks Dinner had a post on Pressure Cooker Roasted Sweet Potato Puree, based on methods described in Modernist Cuisine at Home (a book I still haven’t been able to convince anyone to give to me as a gift, but it wouldn’t be unusual for you to find me sitting cross-legged on the floor of my local Barnes and Noble leafing through the display copy), so I decided to incorporate that method into my soup.

I think that caramelizing the yams first resulted in a very deep, roasted flavor. The soup really hit the spot in this chilly weather.

Soup-Before-Puree-Final-SmallI topped the soup with parmesan crisps (a recipe I got while watching The Barefoot Contessa, but there are a lot of recipes for it, and since it only has one ingredient there is not a lot of variation) and crumbled bacon, with a swirl of cream. Along with some pickled vegetables, this soup was substantial enough to be the main course.

So, if you are looking for something to warm yourself up on a chilly night, give it a try!
