1In a bowl, add warm water, caster sugar, and instant yeast. Mix well, cover, and let it proof for 10 minutes.
2Add milk, cooking oil, and gradually add all-purpose flour and pink salt. Mix well for 10-12 minutes.
3Add the remaining all-purpose flour, mix well, and knead until the dough is formed.
4Transfer the dough to a greased working surface and knead with wet hands for 8-10 minutes.
5Add cooking oil and knead until a smooth dough is formed. Grease with oil, cover with cling film, and let it proof for 1 hour or until double in size in a warm place.
6For a large (14-inch) pizza, use 380g of dough; for a medium (12-inch) pizza, use 270g; and for a small (8-inch) pizza, use 130g.
7Make smooth dough balls, place them on a greased tray, and grease the dough balls with cooking oil. Cover with cling film and freeze for at least 24 hours, or until rock-hard.
8Store frozen dough balls in separate zip lock bags for up to 4 months in the freezer.
9Take out the dough balls from the freezer.
10Spread cornmeal on a pizza tray, place the frozen dough ball on top, and sprinkle with more cornmeal. Cover with cling film and let it thaw at room temperature for 3-4 hours.
11Gently press to spread the dough and apply cooking oil on the side of the dough.
12Spread pizza sauce, add cheddar cheese, chicken filling, mozzarella cheese, crushed red chili, dried oregano, and black olives.
13Bake in a preheated oven at 180°C until the cheese melts (12-15 minutes).
