If you want to kick up the heat in your chili, try adding fresh jalapeños or serrano peppers for a nice kick!

You can also use hotter chili powders like cayenne or chipotle to add both heat and a smoky flavor. Another great trick is to toss in some crushed red pepper flakes or a dash of hot sauce for an extra boost. Just be careful to balance the heat with some sweetness or acidity, like a bit of brown sugar or lime juice, to keep the flavors well-rounded. Enjoy your spicy chili!
