Follow these simple, step-by-step instructions to assemble your Tomato Mozzarella Stacks perfectly. The process is straightforward and focuses on careful preparation and layering to build a beautiful and stable tower of flavor.

1. Prepare Your Ingredients: The first step is to get all your components ready, a culinary practice known as mise en place. Wash and gently pat dry your tomatoes and basil leaves. Remove the fresh mozzarella ball from its liquid and pat it thoroughly dry with paper towels. This is a critical step; excess moisture will make your stacks slide and can create a watery pool on your serving platter.
2. Slice the Tomatoes and Mozzarella: Using a very sharp serrated knife (a bread knife works wonderfully), carefully slice the tomatoes into uniform rounds, approximately 1/4 to 1/3-inch thick. A serrated knife will cut through the tomato skin without squishing the flesh, ensuring clean, beautiful slices. Discard the very top and bottom ends of the tomato or save them for another use. Next, use a sharp, non-serrated knife to slice the mozzarella ball into rounds of a similar thickness to your tomato slices. Aim for uniformity, as this will help your stacks stand tall and look professional.
3. Season the Tomatoes: Arrange the tomato slices in a single layer on a cutting board or a large plate. Lightly sprinkle all of them with coarse sea salt and a touch of freshly ground black pepper. Let them sit for a few minutes. The salt will begin to draw out some of the excess water while simultaneously enhancing their natural sweetness. This step is a secret to a more intensely flavored and less watery stack.
4. Begin Assembling the Stacks: Now for the fun part. Start building your stacks directly on your serving platter to minimize movement later. Begin with a single slice of tomato as the base. Place it down and ensure it’s stable.
5. Layer the Ingredients: On top of the tomato base, place a slice of fresh mozzarella. Follow this with one or two large, whole basil leaves. You want the green of the basil to peek out from the sides.
6. Repeat the Layers: Continue this layering process: another slice of tomato, another slice of mozzarella, and another layer of basil leaves. You can typically create a stack with three to four layers of tomato and mozzarella, depending on the sturdiness of your slices. End with a final slice of tomato or mozzarella on top for a clean finish.
7. Create All the Stacks: Repeat the layering process until you have used all of your tomato and mozzarella slices. You should be able to create about four to six impressive stacks, depending on the size of your ingredients. Arrange them on the platter with enough space to allow them to be the star of the show.
8. The Final Flourish: Just before serving, drizzle the stacks generously with your high-quality extra virgin olive oil. Let it cascade down the sides. Then, artfully drizzle the thick balsamic glaze over the top and around the base of the stacks on the platter. Finish with one last, light sprinkle of coarse sea salt and freshly ground black pepper over the very top. Garnish with a few extra small basil leaves if desired. Serve immediately for the best flavor and texture.
