Getting consistent pizza results can be trickier then one would think. A few tips to help.
Use a scale and weigh your ingredients. This is especially important with the flour. It is really hard to get the same amount of flour time and again if you use dry measuring cups. Same goes with water.
With pizza toppings, in most cases less is better especially if your trying to load up a bunch of different toppings. Also be mindful of the water content in some vegetable toppings.
Always make sure your kamado is properly heat soaked including the pizza/baking stone. This assures you that pizza from one night to the next will cook the same.
Once you figure out cook times, no peaking. Opening the dome lets a lot of heat escape. To get a look towards the end of the cook just Crack the dome open just enough to see inside and close immediately if it's not done. Constantly looking will cause your crust to finish before the toppings.
Follow the recommended cook temperature for the dough recipe your using. Each different dough recipe was formulated for a specific temperature range. If you go outside that range your results will not be optimum.
And lastly don't get frustrated and give up. One will experience many pizza fails on the road to perfection.
