Korean BBQ Beef
Grated Korean pear does two jobs in this marinade: its enzymes soften the thin slices of sirloin, and its sugars meet the soy sauce to form the sweet, salty gloss that bulgogi is recognized by. Whether that gloss forms depends on the pan. When all the beef goes into the pan at once, the temperature drops and the meat stews in its own liquid, turning gray and chewy instead of browning at the edges. Onion and scallion marinate alongside the beef and soak up the same seasoning. Spoon it over rice or wrap it in lettuce.
