Leek Soup with Cheese Dumplings

In large saucepan, melt butter over medium heat; cook leeks and onion, stirring often, until softened, about 10 minutes. Stir in flour and pepper; cook for 1 minute.

Stir in wine; increase heat to medium-high. Boil until reduced by half, about 3 minutes. Stir in stock and salt ; bring to boil. Reduce heat; cover and simmer for 20 minutes. (make-ahead: Let cool for 30 minutes. Refrigerate until cold. Transfer to airtight container and refrigerate for up to 2 days. Or freeze for up to 2 weeks. Thaw in refrigerator for 24 hours.)

Cheese Dumplings:
Meanwhile, using fork, mash together cheese, flour, butter, egg, parsley, salt and pepper to make firm dough. With lightly dampened hands, roll tablespoonfuls (15 mL) of dough into balls; place on plate. Drop all at once into simmering soup. Simmer until dumplings float to surface, about 10 minutes.

Tip:
To clean and chop leeks, trim off and discard dark green parts by slicing inward at a sharp angle toward tops of leeks to save inner light green parts. Cut off root ends and split lengthwise. Clean thoroughly under running water; chop finely.
