The flavors of the southwest infuse a tender and juicy beef brisket recipe that cooks in your pressure cooker. The beef does need to marinate before cooking, so plan ahead and start this the day before you want to serve it. The marinade, rich in spices and chiles, is really delicious with the tender meat. If you like your food spicy, you can certainly add more chiles. Think about adding some cayenne pepper too, or crushed red pepper flakes. Because this is such a large chunk of meat, it can take the added spices. This wonderful dish should be served with mashed potatoes or cooked polenta to soak up all of the wonderful sauce. Some sliced tomatoes would be an excellent side dish, as would a green salad tossed with sliced mushrooms and an oil and vinegar dressing. For dessert, a cooling ice cream pie or some brownies would be the perfect finishing touch.
