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.

Ranked causes

Most likely

  1. Combining raw toppings with very different natural cook times in a single short bake

    Generally accepted

    Toppings · from Some toppings are done while others on the same pizza are still raw or underdone

    A short pizza bake is not long enough to fully cook a dense raw vegetable or thick raw meat in the same time it takes to finish a naturally quicker-cooking topping.

    Why it fits
    • Recorded cause of "Some toppings are done while others on the same pizza are still raw or underdone", ranked 1 of 3 by PizzaHQ's editors.
    How to tell it apart
    Doneness splits by ingredient across several raw toppings combined in one short bake, rather than one obviously slow ingredient lagging.
    Rescue it now
    If still assembling, remove and pre-cook the slower ingredient before returning it to the pizza; once baked, a brief broiler finish can help catch up any remaining raw spots
    Next time
    Pre-cook naturally slow-cooking toppings before assembly, and cut the same ingredient to a consistent size across the whole pizza

  2. Slower-cooking toppings used raw instead of pre-cooked

    Generally accepted

    Toppings · from Some toppings are done while others on the same pizza are still raw or underdone

    Some toppings (raw sausage, raw dense vegetables) genuinely need a head start before assembly; used raw, they finish long after everything else on the same pizza.

    Why it fits
    • Recorded cause of "Some toppings are done while others on the same pizza are still raw or underdone", ranked 2 of 3 by PizzaHQ's editors.
    How to tell it apart
    The underdone pieces are specifically raw sausage or dense vegetables that went on uncooked, while anything pre-cooked finished on time.

    If still assembling, remove and pre-cook the slower ingredient before returning it to the pizza; once baked, a brief broiler finish can help catch up any remaining raw spots

Also possible

  1. Inconsistent cutting size for the same topping

    Generally accepted

    Toppings · from Some toppings are done while others on the same pizza are still raw or underdone

    Thicker pieces of the same ingredient take measurably longer to cook through than thin ones cut from the same batch.

    Why it fits
    • Recorded cause of "Some toppings are done while others on the same pizza are still raw or underdone", ranked 3 of 3 by PizzaHQ's editors.
    How to tell it apart
    Doneness varies within the same ingredient: thin pieces are done while thicker pieces of it are still raw.

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.
