Pasta spiral with mushroom filling

If you do not want to present this dish as described in the recipe, simply rearrange the ingredients.  Cut the pasta into linguini or fettucini, mix the mushroom filling and the cheese sauce and spoon it over the pasta.  Drizzle the truffle vinaigrette around and sprinkle with some chopped parsley and chives.

Preheat the oven to 180° C  (356° F).

The filling:
1 tablespoon/15 ml olive oil
500 g/17.6 oz mixed mushrooms, finely chopped
2 shallots, finely chopped
1 clove garlic, minced
¼ cup/60 ml chicken stock, heated (use vegetable stock if for vegetarian)
1 sprig of parsley, finely chopped
1 tablespoon/15 ml dried porcini mushrooms, finely ground (not soaked)
salt and freshly ground black pepper

The truffle vinaigrette (optional):
¼ cup/60 ml olive oil
3 shallots, finely chopped
1 teaspoon/5 ml fresh parsley, finely chopped
½ cup/125 ml white wine vinegar
2 teaspoons/10 ml truffle oil
1 tablespoon/15 ml Dijon mustard
salt and freshly ground black pepper
2 teaspoons/10 ml preserved truffle (finely chopped) with the  truffle oil

If you do not have access to truffle, simple omit it from the ingredients list.  The rest still makes a delightful vinaigrette.

The pasta:
100 g/3.5 oz strong flour
100 g/3.5 oz Durham wheat
2 eggs

The cheese sauce:
2 cups/500 ml chicken stock
1 clove garlic, crushed
1 bay leaf
2 sprigs of fresh thyme
3 tablespoons/45 ml butter
3 tablespoons/45 ml flour
50 g/¾ oz Gruyère cheese
4 tablespoons/60 ml fresh cream
a pinch nutmeg, ground
salt and freshly ground white pepper
2 teaspoons/10 ml Parmesan cheese

The garnish:
the reserved mushrooms
a few sprigs of parsley
truffle vinaigrette/vinaigrette

• For the filling, heat the oil and brown the mushrooms (also the whole ones kept for the garnish), add the shallots, garlic, the chicken stock (or vegetable stock), parsley, and the porcini mushroom powder. Simmer for a few minutes until the liquid has reduced, season to taste, then set aside to cool.  Retrieve the whole mushrooms and set aside.
• For the truffle vinaigrette/vinaigrette, mix all the ingredients together and store in a squeeze bottle in the refrigerator.
• To make the pasta, place all the ingredients in a food processor and process until it becomes smooth and silky.  Roll in plastic film and refrigerate for 30 minutes.
• Meanwhile, for the cheese sauce, heat the chicken stock (or vegetable stock) in a saucepan with the garlic, bay leaf and thyme.
• In another saucepan and over medium heat, melt the butter. Stir in the flour and cook for 2 minutes whilst stirring, strain the stock then whisk into the butter mixture, ½ cup/125 ml at a time.
• Whisk until smooth bringing the liquid to a boil.  Reduce the heat to low and cook for 15 minutes.
• Remove from the heat then add the Gruyère cheese, cream and nutmeg, and season with salt and freshly ground white pepper.  Cover the surface with greaseproof paper and keep warm.
• Roll the pasta out thinly and cut into 2 x 4 cm/1.5 in x 50 cm/19.6 in long strips.
• Spread the mushroom mixture over each noodle ribbon and roll the ribbon up in a spiral.
• Place in a steam basket lined with cabbage leaves (rubbed with some oil to prevent it from sticking to the basket) and steam for 10 minutes.
• Carefully remove each spiral and arrange in a greased oven-proof dish. Discard the cabbage leaves.
• Pour the ¾ cup/175 ml of the cheese sauce over the spirals and top with the Parmesan cheese.  Bake in the oven for 10 – 15 minutes until the top is golden and the sauce is bubbling.

To serve, place a spiral on each heated serving plate, spoon around the rest of the cream sauce and garnish with a whole mushroom and a sprig of parsley.  Finally, lightly drizzle the truffle vinaigrette/vinaigrette over.
