I found it for you on the mobile joint food channel:

First make the marinade, smear it on the steak and then grill it.

The specific method is as follows:

1. Wash the apples and pears without peeling and core them, peel the kiwi, peel the onions, garlic cloves and ginger slices and beat them into fine pieces with 200 mL of water. Puree.

2. Pour 400mL soy sauce, 180mL mirin, and half a cup of white sesame seeds into the puree, and stir well.

How to grill steak:

1. Soak the Korean beef flanken rib to remove the blood, and wipe the surface of the meat dry with kitchen paper.

2. Pour bacon sauce on the steak and marinate overnight.

3. Without oil, use a pan or barbecue grill to fry both sides of the steak over high heat. Before putting it in the pan, you can cut the ribs and fry the inside over low heat until the juice is gone.
