For best results, use contrasting colors and shapes on each skewer for an eye-catching presentation, keep ingredients well-chilled before assembling so the cheese stays firm, and pat any very wet items (like mozzarella balls or olives from brine) dry with a paper towel so the meats and cheese don’t get soggy. You can easily customize the skewers with seasonal produce or different cured meats and cheeses and assemble them a few hours ahead, storing them tightly covered in the refrigerator; just add the oil and balsamic drizzle right before serving to keep everything fresh and vibrant.
