Mix together dry activated yeast with 5-6 tbsp of lukewarm water and sugar.
Keep it covered and let it stand for 10-15 minutes or until you see some bubbles popping. This is an important step as it checks if the yeast is activated. If no bubbles are seen, that means your yeast has expired or is not of good quality, hence should be discarded.
In a bowl rub flour and butter together. Add salt.
Add the yeast mixture together with some lukewarm water and knead a loose dough.
Keep the dough covered with a damp cloth or plastic film and leave it undisturbed in a warm place for 45 min or until the dough doubles in size.
When the dough is almost double in size, knead it lightly, shape it in the form of pizza base. Again cover it and let it rest for 15-20 minutes. Till then prepare the pizza sauce and chop some veggies.
