So, I'm following the recipes just for fun while waiting for something to happen (events, finishing tasks, etc). I've managed to cook the other recipes without too much trouble, but I can't seem to get the pizza right.

I got the flattened dough, tomato (tried both cut and uncut), 3 cheese cubes (again, both cut and uncut), topping (so far I tried the sausage option), but whenever I put these items on the stove, only the dough is cooked, resulting in a flat bread.

Are there any other steps that I'm missing here?

Craft all the ingredients together on a workbench or cutting board to actually make them a pizza to cook, you are effectively just stacking a pile of whole ingredients on top of flattened dough and hoping it turns into a pizza when you cook it.

I've tried again after reading your comment, and discovered that this was a mistake on my part.

I was trying to use a cooked sausage instead of a raw one, therefore the only "crafting" option was the tomato seed pack. I've just put all ingredients on the crafting bench in hopes that the pizza option would appear, and the raw shrimps made it into a shrimp pizza. So yeah, my mistake for using the cooked sausage, whoops.

Thanks for the help!
