As other already wrote, it's a griddle. It went a little bit faster then usual. I'm limited to a gas oven with only bottom heat, no fan. I tend to start high and then lower the temperature.
I started baking pizza on the griddle as it rarely sticks and I think it's slightly easier then the 12" skillet.
For comparison, this is a 400gr dough base absolutely loaded with toppings.
Looks tasty! Definitely sometime I'm going to try myself. How is that loaf pan working out for you? I've been eyeballing one from petromax as it comes with the lid for making casino breads.
