Preheat the oven to 350°F (175°C).
In a pot, combine the white wine and sliced pears. Simmer for 5-7 minutes until the pears are slightly softened. Drain and set aside.
In a mixing bowl, whisk together the eggs, milk, black pepper, cumin, honey, olive oil, garum, and raisin wine until well combined.
Mash the pears and drain the excess liquid. Pour the egg mixture over the pears, ensuring they are evenly coated.
Bake for 30-40 minutes, or until the custard is set and slightly golden on top.
Remove from the oven and let cool for a few minutes. Garnish with chopped walnuts and fresh mint leaves before serving.
