Can I assemble this sandwich ahead of time?
Assemble no more than 2–3 hours ahead to prevent the bread from becoming soggy. Keep it wrapped in parchment at room temperature. For longer storage, layer ingredients separately and assemble just before serving.
What's the best way to slice the focaccia?
Use a serrated bread knife and cut horizontally through the middle with a gentle sawing motion. A steady hand and slight angling prevents crushing the airy crumb.
Can I substitute the burrata?
Yes. Fresh mozzarella, stracciatella, or ricotta work well. Burrata's creamy center is ideal, but these alternatives maintain the soft, luxe layer the sandwich needs.
Is this sandwich vegetarian-friendly?
Not as written—it contains three deli meats and prosciutto. Omit all cured meats and double the arugula, burrata, and spreads for a vegetarian version.
How do I prevent the Calabrian chili paste from overpowering the sandwich?
Use a thin, even layer—about 1 teaspoon spread across the inside of each bread half. Its heat and vinegar notes are potent; less is more unless you love intense heat.
