In a mini food processor, add the pralines and pulse until pralines are finely ground.
In a small bowl, add the room temperature butter and top with the blended pralines. Using a spatula, fold the blended pralines into the butter until well incorporated.
Add a small pinch of Kosher salt to the mixture and fold again.
Serve butter immediately or refrigerate. If refrigerating, bring butter back to room temperature before serving.
