Around here we’re always in search of recipes that are minimal on prep and big on flavor and this Rosemary Grape Agrodolce Sauce Crostini recipe brings it.
Especially when it comes to cocktail party appetizers. To us, the ultimate cocktail party has a variety of bold bites like these Roasted Sweet Potato Chips With Whipped Goat Cheese, Roasted Garlic Pumpkin Hummus With Toasted Pepitas, Oysters With Pomegranate Granita, or this Rosemary Grape Agrodolce Sauce Crostini recipe.
These bites are sweet-sour-tart-salty thanks to the grape agrodolce paired with the prosciutto. And, if you wanted to make it even more indulgent, you could add a smear of burrata to each crostini. Oh, and though we made them here as small bite-sized crostini, you could also make a large bruschetta, add in some arugula, and make it a light meal.
What Is Agrodolce Sauce?
Agrodolce (pronounced “ah-grow-dole-chay”) is the name for a sweet-sour sauce that comes from Italy. It’s used in a variety of dishes to bring a lot of flavor in just a few spoonfuls.
The best-known agrodolce recipe is from Sicily and it’s believed that the idea of agrodolce was first introduced to Italy by the Arabs when they conquered Sicily over 1,000 years ago. With time the recipe spread across the peninsula and you can now find variations of the recipe throughout Italy.
The base combination is something sweet with something sour and acidic (usual vinegar) and finished with wine and butter, but the specific sweetener and vinegar vary from region to region. The most common vinegar is balsamic but you can also find white or red wine vinegar. Also, some variations include herbs to add another layer of flavor.
How Can You Use Agrodolce Sauce?
You’ll find agrodolce sauce paired with pearl onions or served over grilled meat, as a pasta sauce, as a garnish to a cheese board, or even as a dessert sauce. We particularly like it over seared pork chops, on top of grilled salmon, or with eggplant like a variation of caponata.
