Howdy,J.
How'd the sauce shows go,and when ya coming our way ?
You want to open them for sure.
If you are doing a bunch,you can shuck them, poach them slightly,and single layer in shallow pans.
A little of the mixture below keeps them moist and gives some soppin's for your fresh bread.
You'll have to judge how much smoke you like.
I'd think it would take about 45 mins.,after you close up and start smoking.The edges will thin and curl a little.
The other approach is like Drago's in New Orleans.
Open,leave on the half shell,and add a mixture of butter,chopped garlic,parsley, pepper,and chopped shallots.
They add a pinch of parmesan/romano cheese to each,when they go on the grill.
Hickory goes nicely.
I'd do them at 250�, and depending on their size it could take 20 to 45 mins.
If you are using your egg,cook over med-high direct heat ,add some white wine to the butter,and baste to keep them moist.
Take them off when the edges curl and they are puffed.
Maybe 8 minutes for large oysters?MMMM!
Emeril has Ancho-BBQ Oysters on his site,that put the tops back on the shells to grill.
I Have no experience with them.
Hope this helps a little.
