TOMATO AND ORANGE SOUP

Steps:

• If using ripe tomatoes, wash, core and cut them into chunks, reserving any juice.
• In a wide nonreactive saucepan or skillet, melt the butter, then stir in the onion and the fresh or canned tomatoes and their juices. Cook over medium heat for 2 minutes. Add the stock, cover and simmer gently for 15 minutes. Remove from heat, and puree in a food processor or put through a food mill. Stir in the orange juice and mint or basil. Season to taste with salt and pepper. Cover, and chill 3 hours or overnight.
• To serve, ladle into bowls and, if desired, garnish with an orange slice or cherry tomatoes and a sprig of mint or basil.
