**Test Kitchen Tip:
Because chile peppers can contain volatile oils that can burn your skin and eyes, avoid direct contact with them as much as possible. When working, with chile peppers, wear plastic or rubber gloves. If your bare hands do touch the peppers, wash your hands and nails well with soap and warm water.
*Test Kitchen Tip:
The internal color of a burger is not a reliable doneness indicator. A beef patty cooked to 160 degrees F is safe, regardless of color. To measure the doneness of a patty, insert an instant-read thermometer through the side of the patty to a depth of 2 to 3 inches.
