Warm the olive oil in a saucepan over medium heat. Once it is shimmering, stir in the garlic powder. Almost instantly, add the tomatoes. Add a pinch of salt and sugar, and submerge the basil sprigs.
Once the sauce is bubbling, reduce the heat to low and allow it to simmer while you prepare your pizza.
When you're ready to use the sauce, remove the basil sprigs, check to see if it needs more salt if it is too bland or sugar if it is too acidic. Using a stick blender, blitz until smooth OR carefully transfer to a food processor or blender and blend until smooth.
