Pat the shrimp dry. Moisture is the enemy of a good sear.
Use paper towels to dry them well, then season lightly with salt and pepper.
Make the sauce. In a bowl, whisk honey, soy sauce, minced garlic, lemon juice, sesame oil, and sriracha (if using). Taste and adjust—add a bit more honey for sweetness or soy for salt.
Heat the pan. Set a large skillet over medium-high heat and add the neutral oil. You want it hot but not smoking.
Sear the shrimp in batches. Lay shrimp in a single layer and cook 1–2 minutes until pink on the bottom and slightly curled.
Flip and cook another 30–60 seconds. Remove to a plate. Don’t overcrowd the pan—work in two batches if needed.
Deglaze and sauce. Lower heat to medium.
Pour in the sauce, scraping up any browned bits. If you want it thicker, stir in the cornstarch slurry and simmer 30–60 seconds until glossy.
Coat the shrimp. Return shrimp to the pan and toss to coat, cooking 30 seconds more. The sauce should cling and look shiny.
Finish and serve. Top with green onions and sesame seeds.
Serve immediately over rice, noodles, or alongside steamed broccoli or snap peas.
