Diagnosing a Pizza That Went Wrong

Pizza failures are consistent enough to be diagnosed from the result. Each characteristic problem has one or two likely causes, and knowing which saves changing the wrong variable.

Pale, Bendy Base

Not enough heat, almost always. Either the oven does not reach a high enough temperature or the stone was not properly preheated.

The fix is a longer preheat and the hottest setting available. Baking longer does not help; it dries the pizza without crisping the base.

Soggy Centre, Crisp Rim

Too much moisture on top. Fresh mozzarella undrained, watery vegetables added raw, or simply too much sauce.

Drain the cheese, pre-cook anything watery, sauce thinly. This is the single most common home pizza problem and it is entirely a topping issue.

Burnt Base, Undercooked Top

• Too much bottom heat relative to top
• Stone too hot for a heavily loaded pizza
• Where an oven has separate dials, reduce the bottom and raise the top
• Otherwise move the pizza up, or use a tray on the stone

Ovens with independent upper and lower controls, of the kind at piezano.net, make this adjustable rather than something to work around, and it is the main technique available during a four-minute bake.

No Rim, Flat All Over

Either the rim was pressed during shaping, or the dough was rolled with a pin, or it was over-proved and had no gas left.

Leave the outer inch untouched when shaping, and use hands rather than a roller for any style that should puff.

Dough That Will Not Stretch

Too cold, or not rested long enough. Gluten needs to relax before it will extend.

Take dough out of the refrigerator one to two hours before shaping, and if it springs back, cover it and wait ten minutes rather than forcing it.

Tough, Dense Crust

Usually under-fermented: not enough time, or too cold a rise, or dead yeast.

Yeast loses potency gradually with no visual warning. Testing it in warm water with a pinch of sugar takes two minutes and rules out the most common invisible cause.

Sticking to the Peel

Time on the peel, not technique. Every extra minute lets the dough absorb the dusting and bond.

Shape elsewhere, transfer to the peel last, top quickly, and shake before topping to confirm it moves.

Bitter or Smoky Flavour

Burnt semolina and old residue on the stone. Scrape it when cool between sessions.

Excess dusting flour is the usual culprit, so a lighter hand on the peel improves the taste as well as the launch.

Cheese That Goes Grainy

Pre-grated cheese, which carries an anti-caking starch that prevents smooth melting. Grating your own resolves it entirely.

Change One Thing at a Time

The most useful diagnostic habit. Changing hydration, flour and oven setting simultaneously tells you nothing about which mattered.
