These are simple to make and really good. I find that stuffed mushrooms with bread crumbs tend to be dry. These have no bread crumbs, therefore, they are very juicy and moist. They have a little kick to them. I did add a little more mayonnaise as I thought the mixture was a little dry. I also omitted using the radicchio. I used a large can of crab claws found in the refrigerator section. The recipe originally calls for 12 ounces of mushrooms but I found that I had alot of mixture left over. These can be made ahead of time and then pop them in the oven at the last minute.
