Sift flour and salt in a bowl. Rub in chilled butter with your fingertips until it resembles coarse breadcrumbs. This can be done in food processor as well.

Now adding a teaspoon of water at a time bind the dough together. Do not add all the water at a time, this might make dough soft. We need firm, smooth dough.

Once dough comes together do not knead it too much, else butter will start melting.

Wrap the dough with cling foil and refrigerate for at least 30 minutes before rolling, this can be done one or two days before as well.

While preparing filling, keep the dough at room temperature.

To prepare the filling, dissolve flour in ¼ cup milk and set aside.

Heat olive oil in a pan, saute onion and garlic until translucent. Add the flour mixture and saute for another 5 minutes.

Add the boiled macaroni, salt, pepper, mixed herbs and flour mixture along with remaining milk. Let it simmer over low flame until sauce is thick and creamy for about 5 – 10 minutes. Switch off the gas and let the filling cool.

Preheat the oven at 180 degree celsius. Grease a 9 inch pie dish with oil or butter.

Roll out the crust dough into a ½ inch thick and 10 inch round on a lightly dusted floured surface.

Line your pie dish with the pastry, trim of the excess dough from the edges, prick the centre with a fork and put in fridge for 10 – 15 minutes.

After 15 minutes blind bake (see here) the pastry for 15 minutes.

Once pastry is cooked, spoon the macaroni filling into the pastry crust, sprinkle with grated cheese and bake for 30 minutes or until top turns golden brown.

Once done, sprinkle basil leaves and grilled tomatoes on top, drizzle few lugs of olive oil and serve hot.
