A premium appetizer deserves a stylish presentation. For a modern look, arrange the bites in straight lines or tight grids on a white marble slab or matte black tray. Avoid clutter: a single thyme leaf or microgreen adds just the right touch of color without overwhelming the clean aesthetic. Use consistent spacing between bites to highlight their geometric symmetry, creating an effortless high-end feel.
