Watch out for exploding hot soup when puréeing the ingredients in the blender! Start out with a small amount and purée in batches.
Ingredient Notes
Water (or vegetable broth) may be used in place of the chicken stock, store-bought broth is fine.
Half-and-half can be substituted for the heavy cream.
Advance Prep
The soup and the cream can be prepared one day ahead. Reheat the soup gently, don't let it boil.
Make It Dairy Free and Vegan
Use oat milk in place of the heavy cream. After sieving the chiles, serve the purée as is (skip the crema).
