I have a question about the recipe "Pommes Dauphinoise (Potatoes au Gratin)" from merrill. Can this be made in advance? If so, how long?

Yes, you can make it a few hours ahead if you'd like. Just undercook it by about 10 minutes, cover and keep in a warm place. Then uncover and put in the oven to finish cooking just before serving.
