A couple of years ago, I sat in on a class on preparing Thanksgiving dinner. The first course was a winter squash soup that, like most such soups I've had, was notable primarily for its insipid flavor and watery texture. So I developed my own recipe. Roasting the squash instead of boiling it intensifies its flavors, while the maple syrup enhances the sweetness of the squash and the horseradish adds a savory note without contributing noticeable heat. The soup is even better if it melds overnight in the refrigerator.
Makes 4 servings
1 (2 1/2- to 3-pound) butternut squash
1 large leek, cleaned and cut into rounds
2 tablespoons butter
3/4 cup buttermilk
3/4 cup chicken stock
2 tablespoons maple syrup
4 teaspoons prepared horseradish
1/2 teaspoon ground cardamom
1/8 teaspoon ground cloves
1 pinch ground nutmeg
Salt to taste
Preheat oven to 400 degrees.
Cut squash in half across equator, clean out seeds and place cut side down in a baking dish. Add about 1/2 inch of water to baking dish and cook until tender, 45 minutes to 1 hour.
Scrape flesh out of squash into a 2-quart bowl. Melt butter in a 2-quart saucepan over medium-low heat and sweat leeks until translucent. Add 1/2 cup buttermilk, 1/2 cup chicken stock and all remaining ingredients. Bring to a simmer and heat thoroughly.
Puree squash mixture and return to saucepan. Soup should be thick, but still thin enough to require a bowl and spoon to eat. Add additional buttermilk and chicken stock to achieve desired consistency. Taste and adjust seasonings — in particular, you may need a bit more maple syrup depending on how sweet the squash was.
