This semolina vs flour on a pizza peel guide breaks down what actually matters, based on real use.
What you dust your peel with has a direct effect on whether your pizza launches cleanly or sticks halfway into the oven. Flour and semolina behave differently at high temperatures, and the type you choose makes a noticeable difference in practice.
How Peel Dusting Works
The purpose of dusting a peel is to create a low-friction layer between the dough and the peel surface, so the pizza slides off cleanly when you launch. Both flour and semolina do this, but through slightly different mechanisms — and each has different failure modes.
Flour on a Pizza Peel
Plain flour (including 00 flour) creates a fine, powdery layer that works well initially. The problem is that flour absorbs moisture from the dough quickly — within 30–60 seconds, it becomes damp and starts to bond with the dough surface rather than sliding under it. This is why pizza sticks when you wait too long after building it on the peel.
Flour also burns faster than semolina at high oven temperatures, which can cause bitter or acrid flavours on the underside of the pizza and leave black residue on your stone.
Semolina on a Pizza Peel
Fine semolina (also sold as semolina flour or durum wheat semolina) is the preferred choice for most pizza oven cooks. Its coarser grain structure means it doesn’t absorb moisture from the dough as quickly as flour, so it stays effective for longer between building the pizza and launching it. It also burns less readily than plain flour, leaving less residue on the stone.
Coarse semolina works too but can leave a gritty texture on the base of the pizza. Fine semolina gives the best results — the ball-bearing effect without the gritty finish.
The Verdict
Fine semolina is the better choice for pizza oven use. It stays active longer, burns less, and leaves less residue on the stone. Most Neapolitan pizzerias use fine semolina (or a mix of semolina and 00 flour) for exactly this reason.
If you only have plain flour, it will work — but you need to move quickly. Build the pizza and launch within 30–40 seconds. With fine semolina, you have more like 60–90 seconds before the risk of sticking increases significantly.
Practical Tips
- Use fine semolina rather than coarse — coarse semolina can leave a gritty base
- Spread a thin, even layer on the peel — too much causes the pizza to slide off before you’re ready
- Lift each edge of the pizza and blow gently underneath before launching to confirm it’s not stuck
- Don’t use cornmeal as a substitute — it burns at high temperatures and tastes unpleasant
- If using flour, move quickly and launch within 30–40 seconds of building
- Keep a small bowl of semolina nearby when building pizzas so you can dust the peel quickly without stopping
