PREPARATION
Step 1
Heat oil in a large, heavy-bottomed pot over medium heat. Add onion, garlic and jalapeño and season with salt and pepper. Cook, stirring occasionally, until onion is softened and translucent, 5 to 8 minutes. Add chile powder and stir to coat. Cook a minute or two to toast the spices, then add chipotles and tomatoes. Season with salt and pepper and cook, stirring occasionally, until the tomatoes start to caramelize a bit on the bottom of the pot, concentrating their flavor.
Step 2
Add vegetable broth, corn and 2 cups of water. Bring to a simmer and reduce heat to low. Simmer until flavors meld and broth tastes rich and flavorful, 15 to 20 minutes.
