Pizza peel
A wide, flat blade to slide the pizza into the oven and take it out when it is ready.
Turning peel
A small, round blade on a long handle to turn the pizza inside the oven.
Can I turn a pizza with a normal pizza peel?
It is possible, but home pizza ovens are often small, which makes turning a pizza inside the oven with a big peel hard. The usual way: take the pizza out with the peel, turn it by hand (careful, hot) and quickly slide it back in. Depending on the oven, you do this at least three times per pizza.
What is the advantage of a turning peel?
You turn the pizza inside the oven, so it stays hot, and you do not have to turn it by hand on the peel.
How do I tell them apart?
A turning peel is round and much smaller. Compared with a 12-inch pizza peel, the blade of a pizza peel is about twice as wide and twice as deep. The turning peel is usually longer overall, because of its long handle.
