Can I substitute Asian pear in this marinade?
Yes. Use 1/4 cup pineapple juice, apple juice, or grated Granny Smith apple. Avoid kiwi or papaya as they may over-tenderize the meat.

Can I make this ahead?
Marinate up to 8 hours ahead. Cook fresh for best texture, or store cooked bulgogi in an airtight container up to 3 days; reheat gently in a skillet over medium heat.
