Pat the shrimp dry. Use paper towels to remove surface moisture. Dry shrimp sear better and stay bouncy rather than steaming in the pan.
Whisk the sauce. In a bowl, combine honey, soy sauce, garlic, rice vinegar, sesame oil, ginger, and sriracha if using.
Taste and adjust for sweetness or salt. You’re aiming for a balanced sweet-salty-tangy base.
Marinate briefly. Toss the shrimp with 2–3 tablespoons of the sauce. Let sit for 10–15 minutes in the fridge.
Don’t go longer than 20 minutes or the texture can turn mushy.
Heat the pan. Set a large skillet over medium-high heat and add oil. You want it hot enough that the shrimp sizzles the second it hits the pan.
Sear the shrimp. Arrange shrimp in a single layer. Cook for about 1–2 minutes per side until pink and slightly opaque with light caramelized edges.
Work in batches if needed to avoid overcrowding.
Make the glaze. Reduce the heat to medium. Add the remaining sauce to the pan. Stir the cornstarch slurry, then pour it in.
Cook for 30–60 seconds until the sauce thickens and turns glossy.
Coat and finish. Return the shrimp to the pan and toss to coat. Season with a pinch of salt and pepper if needed. Remove from heat as soon as the sauce clings to the shrimp.
Garnish and serve. Sprinkle with sesame seeds and scallions.
Serve hot over rice or noodles, or alongside steamed broccoli for a complete meal.
