Ricotta and parsley ravioli

ricotta ravioliServes 6:
To make the pasta:
4 large eggs400g 00 flour
pinch salt
1/2 tablespoon of olive oil
For the filling:
350g fresh ricotta
1 large egg
75 – 100g parmigiano, grated
1/4 tsp nutmeg powder
grated rind of one lemon
1/2 bunch fresh parsely, leaves picked and finely chopped
salt and pepper to taste
For the sauce:
100g unsalted butter
24 fresh sage leaves
grated parmigiano to serve

Make the filling whilst the pasta dough is resting and before rolling it out. To make the filling, simply mix together all the ingredients using a fork until the mixture is homogeneous. Adjust for salt and add pepper if you like. As there is a lot of pasta in this recipe, you should roll out a quarter of the pasta at a time, keeping the remainder wrapped in cling wrap. Make one batch of ravioli as per the instructions and then repeat.
To make the ravioli, place a teaspoon of filling on one half of a rectangle of pasta (our rectangles were about 5cm by 10 cm). Dip a finger in water, wetting the pasta around the filling. Now close the rectangle of pasta like a book so that the filling is enclosed, pressing well around the edges so the raviolo is sealed and there is no air trapped in the filling. Dust the pasta lightly with flour and place on the bench under a tea towel so the pasta does not dry out. Repeat with remaining pasta and filling.
To cook, heat a large pot of salted water until boiling and cook the ravioli for 5 to 7 minutes, until cooked. Whilst they are cooking, make the burnt butter by heating up the butter in a medium sized frypan, until the butter melts and add the sage leaves. Cook for a few minutes until it starts to turn brown. Drain the ravioli and spoon on the burnt butter sauce, decorating with a few crispy sage leaves. Some grated parmigiano is lovely on top of this as well.
