Quick and Easy Sweet Potato Soup
To avoid dirtying a blender and a bowl, use an immersion blender right in the pot.
Optionally, saute onions and garlic in a small amount of oil or butter in the pot before adding sweet potatoes.
Any ingredient can be substituted: you can use butternut squash instead of the sweet potatoes; 1/2 teaspoon of orange extract instead of the liqueur; vegetable stock or water instead of the chicken stock; different spices, according to your own taste.
If you like your soup sweeter, add a tablespoon of maple syrup or brown sugar.
