Drain excess liquid from the marinated lamb. Add cornstarch gradually, tossing until every piece is evenly coated.

Heat 45 ml oil in a large skillet over medium-high heat. When hot, add lamb pieces and distribute to avoid overlap. Cook undisturbed until golden on the bottom, about 1 minute. Flip and cook the other side until just colored, with the interior still pink, 30–40 seconds. Transfer to a large plate.

Add the remaining 15 ml oil, dried chilies, minced ginger, and sliced garlic to the pan. Stir-fry briefly until fragrant. Incorporate onion and cook about 1 minute, just until starting to soften.

Return lamb to the pan. Sprinkle over the prepared spice mix and immediately stir to coat lamb and aromatics evenly. Taste and adjust salt as needed.
