Can I make this sandwich ahead of time?
Assemble just before serving to prevent the bread from becoming soggy. You can caramelize the peaches and toast the bread in advance, then assemble when ready to eat.
What can I use instead of burrata cheese?
Fresh mozzarella or ricotta are good substitutes, though burrata's creamy center is ideal for this sandwich.
How do I caramelize the peaches properly?
Heat butter in a skillet over medium-high heat, add peach slices, and cook 2-3 minutes per side until golden and slightly softened. Don't overcrowd the pan.
Can I use a different type of bread?
Yes. Ciabatta, sourdough, or regular focaccia work well. The rosemary focaccia adds herbaceous flavor, but any toasted bread will work.
Is this sandwich vegetarian?
No, this recipe contains prosciutto. To make it vegetarian, omit the prosciutto and add roasted red peppers or sun-dried tomatoes for depth.
