1. Slice the beef thinly against the grain. In a bowl, mix soy sauce, brown sugar, garlic, ginger, sesame oil, and optional chili flakes. Marinate the beef for 30 minutes or up to 24 hours.

2. Cook rice according to package directions and set aside.

3. Heat a skillet over high heat, add a bit of oil, and sear the beef in batches for 1–2 minutes per side until caramelized. Remove from heat.

4. In the same or a separate skillet, add oil and cook corn kernels until lightly charred. Stir in chopped cilantro at the end.

5. In a small bowl, whisk together mayonnaise, sour cream, lemon juice, cracked black pepper, and salt to create the creamy pepper sauce.

6. Assemble your bowl: start with rice, layer on the corn and beef, and drizzle generously with the creamy sauce. Garnish with extra cilantro if desired.
