1 egg, lightly beaten with 1 tsp. water (for egg wash)
Method
Preheat oven to 200°C (180°C fan) and line a large baking sheet with baking paper.
Wash and slice the peaches into 1cm wedges. In a small bowl, combine the brown sugar, orange zest, and vanilla essence, stirring until well mixed.
Spread the butter onto the lined sheet in six separate squares or circles. Evenly sprinkle 1/2 tablespoon of the sugar mixture over each butter spot, and drizzle 1/2 teaspoon of honey over each. Arrange the peach slices over the sugar mixture, slightly overlapping, and press down lightly. Scatter the grated Gouda evenly over the peaches.
Unroll the puff pastry and cut it into six equal squares. Place one pastry square over each portion of filling, ensuring it’s fully covered. Press the edges down to seal.
Brush the pastry tops with the egg wash and prick the centre of each with a fork. Bake for 25-30 minutes until the pastry is golden brown and puffed, and the caramel base is bubbling around the edges.
Remove the baking sheet from the oven and allow the tarts to cool for 5-10 minutes. Place a flat serving plate or board over the tarts. Working quickly and carefully, firmly flip the baking sheet and the board together. Gently peel the baking paper away from the tarts.
Serve warm with ice cream or a generous dollop of whipped cream.
