Preheat your oven to 400°F. Line a large, rimmed baking sheet with high-heat-resistant parchment paper.
Place the meatball ingredients (ground beef, cilantro, garlic, ginger, red pepper flakes, soy sauce, and sesame oil) in a medium bowl. Use your hands to combine them.
Shape the mixture into 24 meatballs, each weighing about 20 grams.
Arrange the meatballs on the prepared baking sheet. Bake them until they are cooked through, for about 10 minutes.
Meanwhile, prepare the sauce. In a medium saucepan, whisk together the soy sauce and cornstarch. Gradually whisk in the honey, hot sauce, garlic, and ginger.
Heat the sauce over medium heat, whisking constantly until it thickens into a rich glaze. This should take 3-5 minutes. Turn the heat off as soon as the sauce thickens, but leave it on the cooling burner. Stir in the sesame oil.
Using a large spoon or tongs, transfer the baked meatballs into the saucepan. Gently turn them in the sauce until well-coated.
Serve immediately.
