Jalapeno Chili Peppers can be stuffed, cut and added to sandwiches and burgers, pickled, or added to salsas, relishes, and hot sauces. Jalapeños may not be the fieriest of chiles but they lend a nice spark to salsas, marinades, jellies, and cheeses. Try them raw, roasted, lightly sautéed, or pickled and notice how the heat level and flavor subtly changes with different preparations.
