4. Add the chicken broth and simmer on low until tomatoes are very soft, 20–25 minutes.
5. Remove from heat and add the torn fresh basil.
6. Purée using an immersion blender or food processor (process in batches).
7. Add the cream and purée until smooth.
8. Add salt and pepper to taste.
9. Return to low heat until it reaches your desired temperature.
When entertaining casually, let guests create their own grilled cheese sandwiches to go with the soup. Provide an assortment of fresh loaves and sliced cheeses, and keep the soup simmering on the stove or warming in a slow cooker set on low. Croutons and basil leaves make nice garnish.
