Wrap each bacon slice around a pitted prune and secure with a toothpick if needed.
Heat the lard in a large pan over medium-high heat. Add the bacon-wrapped prunes and cook until the bacon is crispy and fully cooked, roughly 8-10 minutes, turning occasionally.
Remove the pan from heat. Carefully pour in the Beerenauslese wine to deglaze, scraping up any browned bits from the bottom. Season with freshly ground black pepper to taste.
Transfer the bacon-wrapped prunes to a serving plate and serve with sliced baguette on the side.
