Is it adviseable to use prosciutto in place of speck?

Using prosciutto in place of speck is possible, but it may alter the dish's flavor profile. Prosciutto is typically sweeter and more delicate, while speck has a smokier and spicier taste due to its curing process. If the unique flavor of speck is essential to the recipe, consider finding a smoked ham or another alternative that retains that distinctive taste.
