Potato-leek is an easy and elegant winter soup.

Like garlic and onions, leeks belong to the genus Allium. Resembling an overgrown shallot, leeks have tough, green tips tapering to tender leaves and a white root. Its flavor is similar to onions, but sweeter and more subtle than its more common relative. In season throughout the winter months, leeks can be roasted, boiled or fried and served on their own or used raw in salads, but the compelling flavor of leeks finds no better home than in a piping-hot bowl of soup.

A favorite cold weather soup, potato-leek relies on potato and cream for its texture, the gentle bite of leeks for its bite and a splash of balsamic vinegar to bring it all home. Elegant, yet easy to make, this rich, silky soup can be served as a side dish or accompanied by a slice of brown bread to make a satisfying meal on its own. Although leeks can be found year round these days and soup is always welcome on the menu, this soup is best enjoyed looking out the window on a snowy day, while you contemplate how good it is to be inside.

A word on cleaning leeks. Leeks trap dirt easily and, if not thoroughly washed, may be gritty. Peel away outer leaves, cut lengthwise and rinse the leek under cold water, pulling its layers open to remove trapped dirt. After slicing the leeks into small sections, placing the pieces in a colander and giving them a final rinse is an easy way to ensure all grit has been dislodged.
