Salmon, Fennel & Potatoes en Papillote with Dill Butter

I took someone else's idea from the Food52 cookbook club on Facebook, to do in aluminum foil since I didn't have parchment paper. Daughter and I loved it but hubby and son didn't care for it at all. Neither of them are big fish fans. I liked that several of the recipes in this book use some of the same ingredients. For instance this is the second recipe using some of the Dry Vermouth I bought. I have a few more marked to use up more of the vermouth.
