| 1/2 cup boiling water | salt and freshly ground black pepper | |
| 1/2 oz dried porcini mushrooms | 6 tbsp chive hollandaise sauce | |
| 2 tbsp butter | chopped fresh chives, for garnish | |
| 14 oz cremini mushrooms, sliced | 1 1/4 cups all-purpose flour, plus extra for dusting | |
| 1 small onion, finely chopped | 6 tbsp butter, chilled and diced | |
| 1 tbsp fresh lemon juice | 1 egg yolk mixed with 2 tbsp water | |
| 4 oz cream cheese |
To make the filling, soak the dried mushrooms in the boiling water for 20 minutes to soften. Drain and chop the soaked mushrooms. Heat the butter in a frying pan over medium-high heat. Add the mushrooms and onion and cook 5 minutes, until the mushrooms are softened. Add the soaked mushrooms and cook about 5 minutes more, until the mushrooms are sizzling. Stir in the lemon juice. Let cool. Pulse the mushroom mixture and cream cheese in a food processor until combined. Season with salt and pepper.
Meanwhile, make the pastry. Pulse the flour and butter in a food processor until it resembles coarse bread crumbs. Add the egg mixture and pulse just until it clumps together. Gather into a disk, wrap in plastic wrap, and refrigerate for 30 minutes.
Have ready the tart pans with removable bottoms. Divide the dough into 6 portions, and roll out each on a lightly floured work surface into a ... in (3mm) thick round. Line each pan with a round, trimming the excess dough. Prick the dough with a fork. Refrigerate for 30 minutes.
Preheat the oven to 400°F (200°C). Line each tart pan with parchment paper and fill with baking beans. Bake for 10 minutes. Remove the paper and beans and bake until the crusts are lightly browned, about 5 minutes more. Remove the pans from the oven. Reduce the oven temperature to 375°F (190°C).
Spread the mushroom mixture in the pastry shells. Top each with 1 tbsp hollandaise sauce. Bake for 10 minutes, until the hollandaise glazes. Remove the tarts from the pans and transfer to plates. Sprinkle with chives and serve hot.
