Troubleshooting
Diagnostic questions, likely causes ranked by confidence, an immediate rescue action, and how to prevent it next time — organised by the stage where you’d notice the problem.
Mixing
Bulk fermentation
Balling and cold fermentation
Dough balls merge together during fermentation
A spacing and planning issue rather than a dough-formula problem.
Dough overproofed
A scheduling and temperature-tracking issue; there is no reliable full fix once dough is significantly overproofed.
Dough smells strongly alcoholic
A reliable sign of overfermentation; not spoilage or unsafe on its own, but the dough's quality will suffer.
Shaping
Dough is too sticky
Usually a hydration-versus-skill mismatch rather than a flawed dough.
Dough tears when stretching
Most often a temperature problem (dough shaped too cold), not a fundamentally flawed dough.
Dough snaps back when stretching
A sign the dough needs more rest or more fermentation time, not a hydration or flour problem.
Dough is difficult to stretch generally
Usually a flour-strength-to-fermentation-time mismatch.
Dough has weak structure (deflates, won't hold shape)
Most often overproofing; less commonly, insufficient initial gluten development.
Topping
Toppings are unevenly distributed
A distribution-technique issue, not a recipe or dough problem — fixable with a final visual check before baking.
Toppings or sauce placed too close to the rim
A topping-placement issue specific to rim-forward styles — leaving a bare border fixes it directly.
Too much topping added, pizza is overloaded
A quantity problem distinct from moisture content — even well-drained toppings can still overload a pizza if there's simply too much of them.
Cheese doesn't reach the edges, leaving bald patches
An under-coverage habit distinct from a bare rim border left on purpose — check the edge specifically when topping.
Cheese or toppings slide off before baking (while topping or launching)
A pre-bake handling and adhesion issue, distinct from toppings sliding off when slicing after baking.
Topping in the centre remains cold while the rest is done
Usually a cold-start topping or an overly thick central pile, compounded by under-preheated equipment.
Some toppings are done while others on the same pizza are still raw or underdone
Almost always raw toppings with mismatched natural cook times combined without pre-cooking the slower ones.
Baking
Crust is dense
Usually a fermentation-time or hydration shortfall relative to the intended style.
Rim (cornicione) did not inflate
The three most common causes are a deflated rim, too-cool an oven, or too little fermentation gas.
Crust is pale (won't brown)
Usually an oven-temperature shortfall rather than a dough-formula problem.
Crust is tough
A flour-strength, overworking, or overbaking issue.
Crust is too chewy
Usually a mismatch between the flour's strength and the texture the style is meant to have.
Crust is cracker-like when it shouldn't be
A hydration or shaping-method mismatch against the intended style.
Base is soggy
The most common single cause is under-preheated equipment combined with excess topping moisture.
Base is pale while the top looks done
Almost always a bottom-heat shortfall, most often solved with a preheated stone or steel.
Base burns before the top is done
A top-to-bottom heat imbalance, or an unevenly stretched dough.
Toppings cook before the base
A top-heavy heat imbalance, usually solved by better preheating the bottom surface.
Base cooks before the toppings finish
A bottom-heavy heat imbalance, or toppings that needed pre-cooking.
Cheese burns
Usually a cheese-choice-to-bake-intensity mismatch.
Cheese does not brown
Usually a cheese-moisture-to-bake-time mismatch, not a fault with the cheese itself.
Cheese releases excessive oil
A cheese-choice or overbaking issue.
Pizza sticks to the peel
Almost always insufficient bench flour/semolina or too much time spent on the peel before launching.
Pizza tears during launch
Usually a downstream consequence of the pizza sticking to the peel first.
Pan crust lacks crispness
Usually an under-oiled pan or insufficient preheating.
Sauce burns or blackens in spots
Almost always exposed or thinly applied sauce meeting very high heat with nothing covering it.
Fresh herbs blacken or wilt in the oven
Almost always fresh herbs added before baking instead of as a post-bake finishing touch.
Flour or semolina scorches underneath the base, tasting bitter and burnt
Almost always excess loose dusting flour or semolina left under the dough and exposed to a very hot baking surface.
The centre is doughy or raw while the rest is cooked
A thick, under-heated, or over-topped middle that has not cooked through while the thinner, more exposed rim has — most often a shaping or topping-load problem rather than a bake-time one.
The baking stone cracked
Almost always thermal shock or absorbed moisture rather than heat alone — a stone tolerates very high temperatures well and tolerates rapid change badly.
The outside chars before the inside cooks
A heat-distribution problem rather than a temperature one: the surface or flame is running far ahead of the chamber, and turning, indirect setup, and topping restraint are the fixes rather than a lower setting.
After baking
Pizza is watery overall
Almost always a cumulative topping-and-sauce moisture problem rather than a single cause.
Sauce tastes raw
A sauce-type-to-oven-temperature mismatch — uncooked sauce needs a genuinely hot, fast bake.
Sauce is too sweet
An over-correction for acidity; adjust sugar in small increments next time.
Toppings slide off when slicing or eating
Usually solved simply by resting the pizza briefly before slicing.
Pizza sticks to the pan
Almost always an under-oiled pan or removing the pizza before it has had a chance to release naturally.
Pizza is too salty
Almost always a compounding effect of multiple salty ingredients used together, not any single ingredient alone.
Pizza tastes bland
Usually a seasoning gap somewhere in the dough, sauce, or topping balance rather than any single missing ingredient.
Base loses crispness (or turns soggy) while resting after baking
Almost always trapped steam from resting on a sealed or solid surface, not a fault in the bake itself.
Pizza cools too quickly after baking
Mostly an inherent characteristic of thin, low-mass crusts rather than a fixable fault; serving temperature and timing help most.
Crust collapses, folds, or crumbles when slicing or lifting a slice
Usually underbaking or an overloaded topping weight — though for foldable styles like New York, some give when held flat is expected, not a fault.
Sauce tastes overly acidic or sharp
Usually underripe or naturally sharp tomatoes used without the balancing effect of cooking, salt, or fat — the counterpart to sauce being too sweet, in the opposite direction.
