Pizza troubleshooter

Choose what you saw — up to three things — and, if you know them, what you baked on, the style and the bake. PizzaHQ ranks the likely causes from its 57 documented symptoms, 137 recorded causes and 36 equipment-specific branches, and for each one says why it fits, how to tell it apart from its neighbours, what you can still rescue, and what to change next time.

2. What did you see? Choose up to 3.

Ranked causes

Most likely

  1. Toppings added in a pile and spread outward rather than scattered directly

    Generally accepted

    Toppings · from Toppings are unevenly distributed

    Spreading a central pile tends to leave the centre heavier and the edges thinner, the opposite of an even scatter.

    Why it fits
    • Recorded cause of "Toppings are unevenly distributed", ranked 1 of 3 by PizzaHQ's editors.
    How to tell it apart
    The unevenness is radial: a heavy centre and sparse edges, after spreading toppings outward from a central pile.
    Rescue it now
    Before baking, do a final visual pass and manually redistribute any obviously bare or overloaded patches
    Next time
    Scatter toppings directly across the whole surface in a light, even pass rather than piling centrally and spreading outward

Also possible

  1. Working on an unstable or moving surface while topping

    Supported, with regional variation

    Workflow and timing · from Toppings are unevenly distributed

    Toppings shift toward whichever side is lower or receives more handling if the peel or pan isn't held level and still.

    Why it fits
    • Recorded cause of "Toppings are unevenly distributed", ranked 2 of 3 by PizzaHQ's editors.
    How to tell it apart
    The toppings have drifted toward one side, matching where the peel or pan was tilted or handled most.

  2. Too many toppings added at once without a deliberate pattern

    Generally accepted

    Toppings · from Toppings are unevenly distributed

    Beyond a handful of pieces, random scattering by feel becomes unreliable — a light, deliberate second pass over any visibly bare patches corrects most of the unevenness.

    Why it fits
    • Recorded cause of "Toppings are unevenly distributed", ranked 3 of 3 by PizzaHQ's editors.
    How to tell it apart
    The unevenness is random patches rather than radial or one-sided, with many pieces scattered by feel at once.

How this works

Every cause shown is one PizzaHQ has already documented, either on a symptom page or as an equipment-specific branch. The troubleshooter does not invent causes; it ranks the documented ones against what you told it.

A cause starts from its recorded evidence confidence and its editorial rank within its symptom. An equipment-specific cause for the equipment you used rises sharply, and causes for equipment you are not using are set aside. A kind of cause (bake environment, fermentation, toppings…) that also explains another thing you saw rises again — one explanation for two observations is more likely than two separate faults.

If you name a style, its recorded equipment fit, bake temperature and bake time are compared with yours; a bake far outside the style's range, or equipment PizzaHQ records as a compromise for that style, raises the heat and equipment causes and says why.

Assumptions

  • Causes are bucketed — most likely, also possible, less likely — rather than given a percentage; the underlying ranking is additive and every addition is listed under 'Why it fits'.
  • 'How to tell it apart' is the observation PizzaHQ records as distinguishing that cause from the symptom's others.
  • Bake temperature and time only count when a style is chosen, because they are judged against that style's recorded range.

Limitations

  • Only documented symptoms can be diagnosed. If what you see is not listed, the closest symptom page is the better starting point.
  • Equipment-specific branches exist where equipment genuinely changes the answer; most dough-stage problems have none, by design.
  • A ranking is a starting point for checking, not a verdict — the distinguishing observations are there so you can confirm or rule out each cause yourself.
