Asian aromatics and tart green apple are quickly sauteed, drawing out their full flavor, before the remaining ingredients are added. The lingering heat of ginger and chile permeates even robust cuts of beef.
Heat oil in a medium saucepan over medium heat. Add apple, lemongrass, garlic, ginger, chile, and star anise. Cook, stirring, for 5 minutes.
Add the remaining ingredients, and bring to a simmer. Remove from heat, and let cool for 5 minutes before use.
This marinade works best with skirt, flank, or hanger steaks. Marinate the skirt for 4 hours, the flank and hanger overnight, and then grill over medium-high heat to desired doneness.
