Korean Beef Bulgogi

Place the beef in the freezer for 30–45 minutes until firm but not frozen solid — a light crust of frost on the exterior, yielding interior. Using a very sharp knife, slice against the grain as thin as you can manage: 2–3 mm is ideal. Partially frozen meat holds its structure under the blade, allowing cuts that would be impossible with room-temperature beef. Fan the slices in a wide, shallow dish for marinating.

Whisk soy sauce, grated pear, sesame oil, sugar, garlic, ginger, scallion whites, and pepper until the sugar fully dissolves. Pour over the fanned beef slices. With clean hands, massage the marinade into each slice, separating them to ensure full coverage. Cover and refrigerate. Marinate a minimum of 2 hours; 4 hours is the sweet spot. Beyond 8 hours, pear enzymes begin to compromise the beef texture.

Heat a cast iron pan or grill to the highest possible heat until smoking. Work in very small batches — a single layer of slices covering no more than a third of the pan surface. The sugar in the marinade caramelizes instantly on a screaming-hot surface; crowding drops the pan temperature and produces steaming instead of searing. Cook each batch 60–90 seconds per side. The caramelization happens in the first 30 seconds of contact.

Pile the seared bulgogi on a serving platter. Scatter toasted sesame seeds and the reserved scallion greens over the top. Serve immediately alongside steamed short-grain rice, kimchi, and banchan. For ssam, provide perilla leaves and rice for wrapping.
