Primo Round Fredstone Baking Stone, 16-Inch

Which grill does the 16-inch Round Fredstone fit?

It is listed for the Primo Round. The other round Fredstone is 19 inches and fits the same grill with more surface area, so the choice between them is about how much baking room you want, not about which grill you own.

Should I buy the 16-inch or the 19-inch?

The 16-inch leaves more open space around the edge and heats back up faster between bakes. The 19-inch gives you a bigger pizza and more room for a couple of loaves. If you mostly cook one thing at a time and want quick turnaround, the smaller stone is the more practical of the two.

Do I need a heat deflector under the stone?

For baking, yes in practice. Something has to stand between the coals and the food, or the stone is sitting in the fire's direct path and its underside runs far hotter than its top. A deflector makes the heat indirect, and the stone then does its own job of providing an even cooking floor.

Can I leave the stone in the grill permanently?

You can, and the extra mass steadies the grill's temperature. The catch is that it blocks part of your cooking area for anything you want to grill over live fire, and searing above it drips grease onto a surface you would rather keep clean. Most people lift it out for direct cooking.

What can I cook on it apart from pizza?

Flatbread, pita, naan, small loaves, scones and pastry all work, as does anything you want crisped underneath rather than grilled in stripes. It is also useful under a tray of vegetables when you want gentle, even heat instead of scorching from below.
