Place the 00 flour into a mixing bowl, or onto a clean work surface and shape into a mound with a well in the centre.

Crack the egg into the middle and lightly beat with a fork.

Gradually draw the flour into the egg, adding water one teaspoon at a time, until a rough dough forms.

Knead the dough using the heel of your hand for 5 minutes until smooth and elastic.

Wrap in cling film and refrigerate for at least 30 minutes before use.
