Step 1: Prepare your ingredients. Drain the bocconcini if they are packed in water and gently pat them dry with a paper towel. Wash and dry the cherry tomatoes and basil leaves. If using, unroll your prosciutto and gently tear or cut it into smaller, manageable pieces that can be easily folded.
Step 2: Assemble the skewers. For each skewer, start with a cherry tomato, then fold a basil leaf in half (or use a small leaf whole), thread it onto the skewer, followed by a bocconcini ball. If using prosciutto, fold a small piece and thread it next. Repeat this pattern once or twice more, depending on the length of your skewer, ensuring you end with a tomato or mozzarella ball for visual appeal. Arrange the finished Christmas recipes appetizers on a large platter.
Step 3: Prepare the balsamic glaze (if making your own). In a small saucepan, bring 1 cup of good quality balsamic vinegar to a gentle simmer over medium-low heat. Let it gently bubble and reduce for 10-15 minutes, or until it has thickened to a syrupy consistency. It should coat the back of a spoon. Be careful not to let it burn. Let it cool slightly before using.
Step 4: Drizzle and serve. Just before serving, generously drizzle the balsamic glaze over all the assembled Caprese skewers. You can also add a light sprinkle of flaky sea salt and freshly ground black pepper for extra flavor. These Christmas recipes appetizers are best served immediately after glazing to prevent the basil from wilting too much and the tomatoes from becoming soggy.
