I've used Emily Ho's recipe for Korean BBQ Marinade several times for tofu and tempeh dishes. I've never had Asian pear juice, so I usually add a splash of lime juice to help give the recipe a little acidity.

I love Korean food to begin with, and I like that this is one recipe I don't have to adjust because of my allergies to hot pepper--it's not spicy at all.
