Place the cleaned shrimp (with shells on) in a skillet. Add the garlic (to be removed later), parsley, black pepper, and juniper berries. After a few minutes, pour in the wine and let it evaporate, gently stirring the shrimp. Add the diced mango. Remove the garlic, then add the olive oil and sauté for a few more minutes.

Meanwhile, bring a pot of water to a boil for the spaghetti. After a few minutes, the shrimp will be ready. Turn off the heat and let them cool slightly, then peel the shrimp, leaving a few with shells for serving.
