Danbow Back when I was in customer service I know I talked to someone who either said his wife did it exactly how you are explaining it or I talked to the woman who did it, I wonder if I was talking to either you or your wife?!
Wrapping it in foil would keep more moisture in the product, same basic process that some people do when they are smoking ribs. I can absolutely see how this would work and I think the way she is doing it, without a casing, would be more effective when wrapping it in foil. I don’t think you’ll ever convert me from using a casing but we might be making some updates here and when we do I might have access to an oven and will give this a try!
