Or is it a spicy slow cooker recipe? Thats the beauty of sweet and spicy chili you get a delicious helping of both. Sweet and spicy is a magical culinary pairing, and this chili delivers it through a healthy helping of chili peppers and brown sugar. It runs up and down the pepper scale, from red bells and smoky sweet piquillo peppers to fresh jalapeo and cayenne pepper powder. Piquillo chilies add only a light simmer of heat, but they provide a tasty smoky sweetness to assist that brown sugar in the recipe. We recommend using dark chili powder if you have it, too, as it adds a rich, slightly sweet undertone as well. If theres none in your pantry, pick some up from our store.
