Mushroom tartlets

Method

1. Heat the oil and butter in a frying pan over a medium-high heat until foaming, then add the mushrooms, garlic and thyme. Fry quickly until the mushrooms are cooked, being careful not to burn the garlic.
2. Transfer to a bowl and mix in half the goat’s cheese. In a jug, beat together the egg, egg yolks, cream and crème fraîche. Add the truffle oil (if using) and season well.
3. Preheat the oven to 190°C/fan170°C/gas 5. Melt the extra butter, then use to brush the pastry all over. Place 3 strips of filo into each of the holes of a 12-hole muffin tin, overlapping them so the base and sides are completely covered.
4. Spoon the mushroom mixture into the tart cases and pour over the egg and cream mixture. Sprinkle over the remaining goat’s cheese and thyme sprigs, then bake for 20-25 minutes until golden and set. Remove from the tins and serve warm.
