Potato & Leek Soup With Cod

In a medium saucepan, boil the water and add the potatoes, onion, and salt. Reduce the heat, and simmer for 3 to 4 minutes until the potatoes are just cooked. Be careful not to overcook the potatoes, or they will get mushy as the soup finishes. Skim off any foam that forms on the surface of the cooking water.

Add the leeks and simmer until tender, 2 to 3 minutes. Add the cod and simmer for 2 more minutes, or until cooked. Reduce the heat to low, and gently whisk in the butter. This will enrich the soup and give it a creamy finish. Stir in the chives and add a splash of cognac or brandy, if desired. Season with fresh pepper and more salt if needed. Serve in warmed soup bowls.
