To prepare a Argentinean skewers with sherry vinegar steak sauce and grilled scallions 629 recipe, first you need to prepare the ingredients. First, you'll need the following ingredients: 14 cup (60 milliliters) kosher salt, 1 tablespoon (2.5 ml) olive oil, and 2 tablespoons (14 g) minced garlic. You can use any type of garlic you like, as long as it's fresh and not dried out. If you don't have fresh garlic, use dried thyme or tarragon. Then, cut the garlic into 1/4-inch (1.3 cm) slices and add it to the skillet. Heat the oil over medium-high heat. Add the steak and cook until the meat is no longer pink in the center, about 5 minutes. Remove from the heat and set aside to cool. In the same skillet, heat the remaining ingredients until they're just heated through. Once the sauce has cooled, add the beef and stir-fry for 2 minutes, or until it starts to thicken. Serve with the burgers.
