No not an "Egg". Big Green Egg is the brand everyone knows but I have a Primo Oval XL ceramic kamado. Great for grilling. Here's a pic with 20 giant pieces of chicken on it.
and standard size pieces.
It sears a great steak
cooks a mean pizza
and even cooks the Thanksgiving Turkey
The difference (IMHO) is the Oval shape is a little more versatile.
Eggs are also great along with Kamado Joe's and a number of others.
I can see the advantage to that shape/style, if I knew this existed I had forgotten. Thanks for the post and info.
