Pizza topics explained
Baker's percentages, hydration, gluten, heat transfer, browning and more — plus how to store, freeze and reheat — explained with sources and stated limits.
Fundamentals
Baker's percentages
Every ingredient is written as a percentage of the flour weight, with flour fixed at 100%. That makes a formula scale to any batch size and lets you compare doughs at a glance.
Dough hydration
Hydration is the water weight as a percentage of the flour weight. Styles sit in quite different ranges, and a higher number is not automatically better.
Yeast and fermentation basics
Yeast produces the gas that lifts the dough and much of its flavour. The amount of yeast, the time and the temperature trade against each other.
Dough temperature
Dough temperature sets the pace of fermentation. The desired-dough-temperature method uses water temperature to correct for warm or cold flour, room and mixing.
Shaping without degassing
Press and stretch from the centre outwards, leave the border untouched, and let cold dough warm up first. A rolling pin is right for some styles and wrong for others.
Pizza families explained
The catalogue groups styles into loose families by lineage and place. The differences you can taste come down to a few axes: thickness, crust structure, bake and fermentation.
Building a pizza: sauce, cheese and toppings
Less is usually more: a thin layer of sauce, cheese suited to the bake, and restrained, dry-ish toppings. Most home sogginess is a moisture problem.
How it works
How gluten develops
Gluten forms when two wheat proteins meet water. Mixing, folding and time organise it into a network whose stretch and spring decide how a dough opens and holds gas.
Fermentation and enzymes in pizza dough
Yeast makes gas, alcohol and some acids, while flour enzymes turn starch into sugars and slowly loosen gluten. Time and temperature set how far each process goes.
How heat gets into a pizza
Pizza cooks by conduction from the floor, convection from hot air and radiation from above. Which dominates, and how balanced top and bottom are, explains most oven differences.
Browning: Maillard, caramelisation and char
Crust browns mainly through the Maillard reaction, with caramelisation and then charring at higher temperatures. Dryness, heat and available sugar decide how far it gets.
Moisture and evaporation in a pizza
Every pizza carries a water budget from dough, sauce, cheese and toppings. The bake has to drive enough of it off; what stays behind soaks into the base or pools on top.
How cheese melts, stretches and releases oil
Cheese is a protein network holding water and fat. How much of each it contains, and how hard it is heated, decides whether it flows, browns, stretches or leaks oil.
Oven spring and how the crust sets
In the first moments of a bake, heat expands gas and turns water and alcohol to vapour, inflating the rim until starch and protein set the structure in place.
Storing, freezing and reheating
Storing and reheating leftover pizza
Why leftover pizza turns leathery or soggy, how to store and freeze slices, and how the common reheating methods compare — with food-safety limits taken only from official bodies.
Refrigerating, freezing and thawing pizza dough
How yeast quantity and temperature set a dough ball's useful fridge life, how long to temper cold dough before stretching, and how to freeze and thaw balls with the least damage — with sources' disagreements left visible.
Storing pizza sauce and cheese
Moving opened tinned tomatoes out of the tin, freezing cooked and uncooked sauce, and which pizza cheeses survive the freezer — with the quality effects of freezing on melt and stretch hedged honestly.
Cooking every kind of pizza
Cooking frozen pizza
Why the base and the top of a frozen pizza cook at different speeds, how the common methods compare by mechanism, why a cold tray softens the base, and how thickness changes the choice — with the pack instructions as the baseline throughout.
Making frozen pizza better
The levers that reliably improve a frozen pizza — preheat, surface, shelf, a short finish under the grill, and additions after the bake — and why piling extra toppings on before baking usually backfires.
Cooking chilled and take-and-bake pizza
Why chilled pizzas and take-and-bake pizzas cook differently — one usually has a set crust, the other is raw dough — what that means for tray, shelf and surface, and why the seller's instructions and the use-by date come first.
Using premade and par-baked pizza bases
A par-baked base is already set, so the challenge is moisture rather than cooking the dough: how sauce quantity, topping moisture and surface affect the result, why edges dry out, and when an extra pre-bake helps.
Using bought pizza dough and pizza kits
Why bought dough is hard to stretch straight from the fridge, how to tie warm-up time to the dough's temperature rather than the clock, how to recognise under- and over-proofed dough, and what a pizza kit fixes for you and what it leaves in your hands.
Making pizza the same day
The realistic routes to pizza on the same day — styles whose dough is traditionally made the same day, bought dough, and premade bases — and why a long cold ferment is a flavour choice, not a requirement.
Oven settings and shelf position for pizza
What each common oven setting does — conventional, fan, fan with bottom heat, bottom heat only and grill — which heat source browns which part of the pizza, how shelf position changes the balance, and how to test your own oven.
How to tell when a pizza is done
The signs that a pizza is done — rim, underside, centre structure, cheese, sauce, toppings and pan-pizza crumb — read against what the style is meant to be, with tactile checks that beat colour alone and the narrow cases where a thermometer is the right tool.
Holding and serving pizza for a group
How to run a home pizza night: baking in sequence, holding briefly without steaming the base, when to slice, serving temperature, reheating between batches and the flow that keeps everyone eating hot pizza — with food-safety limits from official bodies.
Ordering and eating out
How to order pizza well
What common menu style names usually mean, how size, area and topping load change how much you get, how to order for mixed groups, the dietary questions to put to the seller, and which styles cope with a journey.
Judging a pizza by its own style
A style-relative way to judge pizza: dough structure, whether the bake suits the style, char versus burning, sauce and cheese balance, structure, freshness and handling — and why a soft Neapolitan centre and a crisp tavern cut can both be exactly right.
What happens to delivery and takeaway pizza, and how to rescue it
The steam, moisture migration and cooling that happen in the box after the oven; how distance, ventilation and stacking change them; collection versus delivery; and how to rescue a soggy pizza by style and equipment — often by simply eating it now.
Buying equipment and ingredients
Buying frozen pizza: what the pack can and cannot tell you
What to look for when choosing a frozen pizza — crust style and thickness, cheese, sauce, topping load, size and whether it suits your oven — which label information helps, and why claims like 'stone baked' and 'artisan' tell you little.
What to look for in a pizza oven
Choosing a dedicated pizza oven by its specifications: the floor temperature it can hold, how much heat comes from above, how quickly the floor recovers between pizzas, the opening and cooking area, fuel, warm-up, turning, where you can legally and safely use it, and why the headline maximum temperature on the box tells you less than it seems.
Choosing a pizza steel or stone: material, thickness and size
Stone or steel, and how thick: what the material of a baking surface changes in a domestic oven or grill, how thickness trades heat capacity against preheat time and weight, how to size it to your oven, how to look after it, and when a steel is more than you need.
Choosing pizza pans and trays: material, finish and depth
For pan and tray pizza, the pan does much of the work. This covers aluminium, blue or carbon steel, cast iron and anodised finishes; gauge; dark versus light; side height for Detroit and deep dish; non-stick versus seasoning; and what perforated pans and screens do.
Choosing a pizza peel: wood, metal, perforated and turning peels
Wood or metal, perforated or solid: what each kind of peel does well, what independent testing found about perforations, how to size a peel against your pizza and your oven opening, when a small turning peel earns its place, and how long the handle should be.
Thermometers for pizza: infrared versus probe
Pizza makers use two kinds of thermometer for different jobs: infrared for the surface of a stone, steel or oven floor (range, emissivity, distance-to-spot ratio), and probe for the inside of food, where food safety rests on a calibrated reading.
Scales, mixers, dough boxes and cutters: what matters
Which small tools earn their place around the dough and the finished pizza: scale resolution for yeast and salt, when a mixer is worth it and how it warms dough, dough containers and boxes, and cutters.
Buying flour for pizza
Flour labels mix three different things: how strong the flour is (protein, W), how refined it is (the Italian 00/0/1/2 types) and what has been added (malt, bleach, bromate). Match strength to your fermentation and additives to your oven.
Buying tomatoes for pizza sauce
For pizza sauce the important label facts are the form (whole, crushed, passata), how watery the contents are, and what has been added. A protected origin tells you where and how the tomatoes were produced, not that they will taste best.
Buying mozzarella and pizza cheese
Moisture and fat decide most of how a cheese behaves on pizza: whether it browns, weeps or oils. Choose by oven and style first, then by taste.
Buying pepperoni and cured meats for pizza
Cured meats change a pizza through fat, salt and how they react to heat. Casing and diameter predict cupping, slice thickness predicts crispness, and some meats are best added after baking.
Buying olive oil for pizza
Olive oil does three jobs on pizza: an ingredient in dough, a frying medium in pans, and a finishing flavour. Freshness matters most for finishing; for baking and pans, an everyday oil does the job.
Buying yeast for pizza
All commercial yeasts make good pizza. The differences are convenience, shelf life and how you measure; freshness matters more than type.
