Ingredients
6 medium sweet potatoes, peeled and chopped
1 tablespoon minced fresh ginger
2 cups chicken or vegetable stock
1 cup water, or as needed
1 lime, juiced
2 cups milk or cream, or as needed

Place potatoes and ginger in large saucepan. Pour in chicken stock and water, and bring to a boil over high heat. Reduce heat to medium low, cover, and simmer until the potatoes have softened, about 30 minutes.
Puree potatoes and lime juice in a food processor, or with a hand blender until smooth. Return soup to saucepan and stir in milk or cream as desired; heat until warmed through.
