Pinch of cayenne
Preparation
Step 1
Wash leek well in a bowl of cold water, then lift out and drain.
Step 2
Cook celery, onion, and leek in oil in a 6-quart heavy pot over moderate heat, stirring occasionally, until softened, about 10 minutes.
Step 3
Add remaining ingredients (vegetables may not be fully submerged) and simmer, covered, until celery and potatoes are tender, about 10 minutes.
Step 4
Purée in batches in a blender until smooth (use caution when blending hot liquids), then force through a fine-mesh sieve into a bowl, pressing hard on solids, then discarding them.
