Identify the grain direction of your skirt steak and slice against it after cooking to break up muscle fibers, ensuring maximum tenderness and balsamic flavor absorption.

The dark brown sugar caramelizes on the grill and balances the balsamic's acidity, creating a complex glaze—don't skip it or your sauce will taste one-dimensional.

Remove excess marinade and pat the steak completely dry before grilling to achieve a deep, caramelized crust instead of steaming the meat.

Skirt steak is thin and cooks quickly (3-4 minutes per side for medium-rare), so use hot grates and watch carefully to avoid overcooking and drying out this lean cut.

Set aside raw marinade before adding raw meat, then reduce it on the stovetop and brush it on the finished steak for an intensified balsamic-Worcestershire flavor boost.
