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
Underripe or naturally high-acid tomatoes with nothing added to balance them
Generally acceptedSauce · from Sauce tastes overly acidic or sharp
Tomato acidity varies significantly by ripeness and variety; a sharp batch used without adjustment tastes noticeably more acidic than a well-balanced one.
- Why it fits
- Recorded cause of "Sauce tastes overly acidic or sharp", ranked 1 of 3 by PizzaHQ's editors.
- How to tell it apart
- The tomatoes themselves taste sharp straight from the tin, before any cooking or seasoning.
- Rescue it now
- Not fixable once baked; a drizzle of good olive oil over the finished slice can help offset sharpness at the table
- Next time
- Taste the tomatoes before committing to a sauce style, cook sauces down further if they taste sharp, and adjust with a pinch of salt or fat before reaching for sugar

Sauce used raw or barely cooked, without the mellowing effect a longer cook provides
Generally acceptedSauce · from Sauce tastes overly acidic or sharp
Cooking a sauce down for longer rounds out sharp acidity as some volatile acids cook off and flavours concentrate and meld.
- Why it fits
- Recorded cause of "Sauce tastes overly acidic or sharp", ranked 2 of 3 by PizzaHQ's editors.
- How to tell it apart
- The tomatoes taste reasonable, but the sauce went on raw or barely cooked and tastes sharper than a cooked-down version.
- Rescue it now
- Not fixable once baked; a drizzle of good olive oil over the finished slice can help offset sharpness at the table
- Next time
- Taste the tomatoes before committing to a sauce style, cook sauces down further if they taste sharp, and adjust with a pinch of salt or fat before reaching for sugar

Also possible
No counterbalancing salt, fat, or small amount of sugar included
Generally acceptedSauce · from Sauce tastes overly acidic or sharp
A pinch of salt or a small amount of fat (olive oil) can round out perceived sharpness without needing to oversweeten.
- Why it fits

- How to tell it apart
- The sauce was cooked, but no salt, olive oil or sugar went into it at any point to round it out.

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.
