How to make
Cut the pork shoulder or pork leg into thick steaks, season them with salt very lightly and tenderize or cut them in several places with a knife.
In a large bowl, pour the wine, the grill spice, sugar and other spices and mix them and then rub them into the steaks well.
Cut the onion into large pieces and the garlic into several pieces.
Cover the bowl with cling film and let them absorb the flavors for a few hours.
