Potato Leek Plus

Saute 1 large leek (chopped) in butter. Add 3 potatoes, chopped, 1 quart seafood stock, and 1–2 t. salt. Simmer until potatoes are soft, about 30 mins. Then mash the potatoes with a ricer, or puree. Optional: Add 1 lb. white fish and continue cooking until the fish is done, and/or thicken finished soup with cream.
