- 4 tablespoons (½ stick) unsalted butter
 - 1 small red onion, minced
 - 4 cups (4 pounds in the pod) shelled fresh peas
 - 1 tablespoon sugar
 - 1 cup chicken stock, preferably homemade
 - 4 ounces thinly sliced prosciutto, cut into thin strips
 - Salt and freshly ground pepper to taste
 - 2 tablespoons chopped fresh parsley
 
- Melt the butter in a medium saucepan over medium-high heat. Add the onion and cook, stirring occasionally, just until softened, about 5 minutes.
 - Stir in the peas, sugar, and chicken stock and simmer covered until the peas are barely tender, about 5 minutes. Stir in the prosciutto and cook 1 minute longer.
 - Using a slotted spoon, transfer the peas and prosciutto to a warmed serving bowl. Reduce the liquid remaining in the saucepan over high heat to a thin syrupy glaze. Pour the glaze over the peas and season with salt and pepper. Sprinkle with parsley and serve at once.
