Preparation

• Heat 2 tablespoons. of the oil in a 5- to 6-quart heavy-duty pot over medium-high heat until hot, about a minute. Add the garlic and onion and cook, stirring occasionally, until the onion begins to soften, 3 to 5 minutes. Stir in the paprika, chili powder, and cumin, cook for 1 minute, and then add the tomatoes and their juice. Stir, smashing the tomatoes against the side of the pot to break them up slightly.
  Add 2 cups water and bring to a simmer. Stir in the chickpeas, corn, bell pepper, jalapeño, and 2 teaspoons salt and cook for 8 to 10 minutes.
  
  While the vegetables cook, heat the remaining 1 Tbs. olive oil in an 10-inch skillet over medium-high heat. Add the almonds and cook, stirring constantly, until golden brown, 2 to 3 minutes. Using a slotted spoon, transfer them to a plate lined with paper towels.
  
  Stir the basil and scallions into the chili. Serve the chili with a dollop of sour cream (if using), more scallions, and the almonds.
