Simmer your balsamic marinade for 2-3 minutes before using to concentrate flavors and reduce acidity, creating a glossier glaze that clings beautifully to the chicken.

Marinate chicken for 4-6 hours maximum—longer marination with acidic balsamic can make the exterior mushy while the interior stays undercooked.

Prepare your strawberry salsa just 30 minutes before serving to keep the berries firm and prevent excess liquid from weeping onto the plate.

Pat the marinated chicken completely dry with paper towels before grilling to achieve a golden crust and prevent the marinade from steaming the meat.

Remove jalapeño seeds and white membranes for controlled heat, or leave them in for a spicy punch that won't overpower the delicate strawberry flavor.
