Spinach & Buttermilk Soup

Directions

Combine spinach and 2 cups broth in a 3- to 4-quart pan.

Bring to boil on high heat; use a spoon to break spinach apart.

As soon as spinach is in chunks, pour into a blender, add 1 tablespoon lemon peel, and purée until smooth.

In pan, mix remaining 2 cups broth with cornstarch until smooth; add spinach mixture.

Stir often on high heat until boiling.

Mix in buttermilk and pour into bowls or mugs.

Sprinkle with remaining peel and add salt and pepper to taste.
