In a small bowl, mix the active dry yeast with warm water (about 37°C) and let it sit for 5 minutes until frothy, indicating the yeast is activated.
In a large mixing bowl, combine the 00 flour and salt. Form a well in the centre and pour in the yeast mixture along with the olive oil.
Mix the ingredients until a dough begins to form. Knead the dough on a lightly floured surface for about 10 minutes until smooth and elastic.
Place the dough in a lightly oiled bowl and cover with a damp cloth. Allow it to rise in a warm place for about 1 hour or until doubled in size.
Once risen, punch down the dough and divide it into four equal portions. Shape each portion into a ball and let rest for 15 minutes before rolling out for pizza bases.
