Chef Bill Kim makes this curry-and-chile-spiced marinade inspired by lechón, a slow-roasted Puerto Rican pork dish that he learned from his mother-in-law. Because the flavors are intense, it's best to scrape off the marinade before grilling.
In a mini food processor, combine the garlic, oregano, paprika, chile powder, curry and salt and process until the garlic is chopped. Add the vinegar and olive oil and process to a paste.
Rub the marinade onto the turkey cutlets and let stand at room temperature for at least 30 minutes or refrigerate for up to 24 hours.
Light a grill. Scrape the marinade off of the turkey cutlets. Brush the cutlets with vegetable oil and grill over moderately high heat, turning once, until lightly charred and cooked through, about 5 minutes total. Serve hot.
The marinade can be refrigerated for up to 3 days.
Variation The marinade is also great for pork chops and pork tenderloin.
