How to make Potato, Salmon and Watercress Tart
Making the Potato, Salmon and Watercress Tart involves a few steps that culminate in a dish that is not only visually appealing but also deeply satisfying. Start by preparing the crust, which forms the foundation for your tart. Use ready-to-use shortcrust pastry to simplify the process. Once the crust is rolled out and lined in the tart pan, it’s chilled to maintain its shape during baking.
While the crust bakes, the filling is created by lightly boiling baby potatoes and sautéing spring onions and watercress, which are then brought together with eggs and heavy cream. This melding of ingredients brings richness and flavor to the tart. The addition of hot-smoked salmon adds a layer of complexity, making it a gourmet dish. After assembling the layers, the tart is baked to perfection, ensuring the filling is creamy and set while the top gains a lovely golden hue.
By following these steps, the finished tart showcases the balance of rich flavors and fresh ingredients. Each slice serves as a reminder of culinary artistry, presenting not only taste but also nourishment. The methodical combination of baking, sautéing, and blending flavors leads to a wholesome masterpiece that can be easily enjoyed by everyone.
Ingredients
- 1 sheet ready-to-use shortcrust pastry, about 375 g
- A little all-purpose flour, for rolling and lining the tin
- 250 g baby potatoes, cut in halves or quarters if they are large
- 30 g butter
- 1 tablespoon olive oil
- 1 small bunch spring onions, thinly sliced
- 85 g fresh watercress
- 3 eggs
- 125 ml heavy cream
- 200 g hot-smoked salmon
- Sea salt, to taste
- Freshly ground black pepper, to taste
Directions
- Roll the pastry on a lightly floured surface and use it to line a 23 cm tart pan, leaving a slight overhang. Prick the base with a fork, chill for 30 minutes, and heat the oven to 190°C.
- Boil the potatoes in salted water for around 10 minutes, until nearly tender but not fully cooked. Drain and set aside.
- In a large pan, heat the butter and olive oil together. Keep a small amount of the green onion tops for garnish, then cook the rest for about 3 minutes until softened. Add the watercress, toss gently in the butter, cover briefly, and let it wilt for 1 minute. Add the drained potatoes and stir to coat everything well.
- Beat the eggs with the cream, then season with salt and black pepper.
- Line the chilled pastry with baking paper and baking beans, then blind bake for 15 minutes. Remove the lining and bake again for 10 minutes until lightly golden.
- Lower the oven temperature to 170°C. Trim the pastry edges neatly by rolling over the rim with a rolling pin.
- Spread the potato, watercress, and onion mixture into the baked crust. Break the salmon into large flakes and scatter them over the filling. Pour the egg and cream mixture into the tart shell. Finish with the reserved spring onion and a little extra black pepper.
- Bake for about 20 minutes, or until the filling is set and the top is lightly golden.
