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. The base is underbaked and hasn't developed enough structure to support its own weight or the toppings

    Generally accepted

    Bake environment · from Crust collapses, folds, or crumbles when slicing or lifting a slice

    A crust that hasn't fully set internally will bend or tear under the weight of toppings and its own structure once out of the pan or peel.

    Why it fits
    • Recorded cause of "Crust collapses, folds, or crumbles when slicing or lifting a slice", ranked 1 of 3 by PizzaHQ's editors.
    How to tell it apart
    The underside is pale, soft or doughy, and the crumb looks damp or gummy when the slice droops.
    Rescue it now
    Support the slice from underneath while lifting, or fold it if the style is meant to be eaten that way; not otherwise fixable once baked
    Next time
    Bake fully through before removing, match topping weight to the crust's structural capacity for the style, and fold rather than fight a style that's designed to be foldable

  2. Topping load too heavy for the crust's thickness and intended style

    Generally accepted

    Toppings · from Crust collapses, folds, or crumbles when slicing or lifting a slice

    Even a fully baked thin crust has a structural limit; toppings beyond that limit cause sagging or collapse when the slice is no longer fully supported.

    Why it fits
    • Recorded cause of "Crust collapses, folds, or crumbles when slicing or lifting a slice", ranked 2 of 3 by PizzaHQ's editors.
    How to tell it apart
    The base looks properly baked and coloured, but the slice droops or breaks under a thick topping layer.
    Rescue it now
    Support the slice from underneath while lifting, or fold it if the style is meant to be eaten that way; not otherwise fixable once baked
    Next time

Also possible

  1. Cutting or lifting technique unsuited to a genuinely soft, foldable style

    Supported, with regional variation

    Workflow and timing · from Crust collapses, folds, or crumbles when slicing or lifting a slice

    Some styles (New York, for instance) are meant to be foldable and will give by design when held flat rather than folded — this isn't a fault if the style is meant to behave this way.

    Why it fits
    • Recorded cause of "Crust collapses, folds, or crumbles when slicing or lifting a slice", ranked 3 of 3 by PizzaHQ's editors.
    How to tell it apart
    The base is fully baked and not overloaded, it is a foldable style such as New York, and it holds once folded.
    Rescue it now
    Support the slice from underneath while lifting, or fold it if the style is meant to be eaten that way; not otherwise fixable once baked
    Next time
    Bake fully through before removing, match topping weight to the crust's structural capacity for the style, and fold rather than fight a style that's designed to be foldable

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.
