Served in demitasse cups, this sophisticated little soup makes an easy-to-handle big-party hors d'oeuvre. For a purely vegetarian soup, garnish with chopped chives. Prep and Cook Time: about 1 1/2 hours. Notes: You can make both the soup and the prosciutto crisps up to 3 days ahead and chill them in airtight containers.

How to Make It

Step 1

Preheat oven to 400°. Melt butter in a large pot over medium heat. Add leek and cook, stirring, until soft and translucent, about 6 minutes. Add garlic and cook 2 minutes longer. Put sweet potatoes in pot; add 3 cups water, 1 1/2 tsp. salt, and 1/2 tsp. pepper. Increase heat to high, bring to a boil, then reduce heat to medium-high and simmer until sweet potatoes are tender, about 10 minutes. Remove from heat and let cool 10 minutes. Working in batches, purée soup until smooth.

Step 2

Prepare the garnish: Spread prosciutto slices on a rimmed baking sheet in a single layer. Bake until crisp, 7 to 10 minutes (watch carefully, as they can burn quickly). Let prosciutto cool completely on baking sheet (about 1 hour), then crumble into tiny pieces and set aside.

Step 3

Transfer puréed soup to a clean pot set over medium-low heat. Stir in cream and up to 2 cups water (enough to make soup easy to drink out of cups). Season to taste with salt and pepper. Serve soup hot, in demitasse cups, garnished with prosciutto or chives if you like.

Step 4

Note: Nutritional analysis is per 1/3-cup serving with 1/2 tsp. prosciutto.

Followed the recipe exactly, except I did not add any additional water at the end. The soup was thick and tasty, and this made a large amount. I did not care for the proscuitto with the soup, however they would be tasty in a salad. This will be a regular for me.

This will be my fourth year of making a double batch of this for Thanksgiving. For simplicity I started using bacon bits (real, not fake!) for sprinkling on top, and for a twist I add a teaspoon or so of cumin to taste. Delicious and very simple.

This soup is wonderfully flavorful. After my party with 18 guests, there only were two servings left over for lunch and someone I work with sweet-talked me into having one of the servings. I emailed her the recipe.
