Shrimp and Andouille Potpies

Make the filling: Melt butter in a large pot over medium heat. Cook leeks until soft but not brown, about 7 minutes. Add sausage and garlic, and cook until sausage cooks through and garlic is fragrant, about 2 minutes. Stir in flour to combine.

Add vermouth. Let cook for 1 minute. Add stock and potatoes, and cook until potatoes are just tender, about 4 minutes. Add shrimp, and cook until opaque, about 1 minute. Let cool. Divide filling among eight 4-inch (12-ounce) ramekins.

Meanwhile, preheat oven to 400 degrees. Make the topping: Roll out puff pastry to a 1/4-inch thickness on a lightly floured surface. Cut out 8 circles that are 1 inch wider than the ramekins; cut a 1/2-inch vent hole in the middle of each. Freeze on a baking sheet for 20 minutes.

Top ramekins with frozen puff pastry, and brush with egg wash. Bake until pastry is golden and filling is bubbling, about 20 minutes.
