Silky Sweet Potato Soup

Are you sick of soup, yet? Neither am I! Good thing, too, because I got a new toy. Way back in the day when my blog was a fresh little newborn, I discovered a trick that guaranteed a velvety vegetable soup. I cooked the vegetables, whipped them in the KitchenAid mixer, and then "strained" them by pressing them through a mesh sieve. It was time and work intensive. I knew the process would be greatly simplified by a ricer. Well, take a look at the America's Test Kitchen recommended tool my parents gave me as one of my holiday gifts! I couldn't wait to give it a spin and instantly had its inaugural soup in mind.

I've made simplistic sweet potato soup before - stew sweet potato chunks in milk/dairy substitute and butter/butter substitute, mash 'em up, and mix with more liquid to reach the desired consistency. Easy peasy! But I knew I could make it smoother and more delicious with a couple tweaks. The leek and turnip add richness and complexity to balance the slight sweetness. You don't need a ricer to make this soup, but if you can get your hands on one, you'll find that the texture goes beyond even velvety, all the way to silken.

Silky Sweet Potato Soup

Feel free to use milk and butter in place of my vegan non-dairy substitutions. Serves 4.

1 bulb leek, dark greens removed, diced
2 medium white/yellow sweet potatoes, peeled, halved lengthwise, and cut into half-inch slices
1 medium turnip, peeled, halved lengthwise, and cut into half-inch slices
4 Tbsp butter substitute (I like Light Smart Balance Buttery Spread)
1 tsp sugar
1/2 tsp salt
4 cups light unsweetened soy milk, approximate

1. Spray large pot with Pam and heat to medium. Sautee leek until soft, 5-10 minutes. Add sweet potato, turnips, butter substitute, sugar, salt, and one cup of the milk. Cover and simmer over medium-low heat until potatoes fall apart with a fork, about 35-45 minutes.

2. OPTIONAL: Strain and reserve cooking liquid. Press vegetables through ricer using medium-holed plate. Discard tough fibrous parts remaining in the ricer's bowl. Add reserved cooking liquid back to the vegetables.

3. Add about a cup and a half more soy milk to the vegetables. Blend using your preferred method: in the blender (may require two batches), with a hand or stand mixer, or with an immersion blender. Return to stove and slowly add more soy milk until desired consistency is reached, approximately one and half more cups. Heat over medium until hot. Salt to taste if desired. Garnish with a sprinkle of brown or turbinado sugar.
