Potage Jacqueline - cooking recipe

Ingredients

2 tablespoons butter
2 cups onions, chopped
1 celery rib, chopped
1 teaspoon fresh ginger, grated
3 medium sweet potatoes, peeled and thinly sliced
4 cups water
1 bay leaf
1/2 teaspoon salt
black pepper
1 cup milk
1/2 cup heavy cream

Preparation

Melt the butter in a saucepan and saute the onions until translucent, stirring every once in a while.
Add the celery and ginger. Cook until the onions brown.
Add the sweet potatoes, water, bay leaf, salt and pepper. Bring to a rapid boil.
Reduce the heat, cover, and simmer 15-20 minutes, until the sweet potatoes are tender.
Retrieve the bay leaf and toss it.
Puree the soup mixture with the milk and cream in a food processor (I needed to do this in two batches).
Reheat gently, adding more salt and pepper is desired.
Don't boil the soup, or it will curdle!
Done!
