Let’s talk about heat! There are so many ways to impart both chile heat and flavor here, and this recipe works with any of them: 1 minced jalapeño or serrano, or more to taste. Ground chile powder (not the spice blend for chili, the dish), chipotle powder, or even smoked hot paprika or cayenne will give it a kick. You could used a minced chipotle from a can, or just a spoonful of the puree around it. You could add some dried chiles, first toasting them in a dry pan, soaking them in hot water until soft, and blending them. Each will change the flavor of the soup slightly, and deepen it.
