Add the soy sauce and water to the carafe of a blender then add, in order, the brown sugar, 4 tablespoons of the scallions, wine, pear, ginger, rice vinegar, sesame oil and Garlic-Infused Oil. Blend until smooth. Taste and season with black pepper and cayenne.

Pour into non-reactive bowl. Add meat to marinade and turn meat over and over to coat thoroughly. Cover bowl with plastic wrap and refrigerate for 2 hours or overnight. (I like to do this in a large zip-top plastic bag, as it is the best way to get the maximum surface area of the meat in contact with the marinade).

Preheat broiler to high with oven rack about 4-inches (10 cm) below heat source. Place a flat rack on a rimmed roasting pan. Remove short ribs from marinade, allowing excess to drip back into the bowl, and arrange ribs on rack spaced out evenly so that they are not touching (you might have to broil in 2 batches).

Broil for 3 minutes, flip short ribs over, and broil for another 3 to 4 minutes or until cooked through and a few char marks show here and there.

Meanwhile, pour leftover marinade into a small saucepan and bring to a boil. Simmer for a few minutes until thick and syrupy, whisking often. Brush short ribs with this concentrated sauce, sprinkle with remaining scallion greens, sesame seeds and serve immediately.
