Tips/Notes
You may need to add another tablespoon of cream to achieve the proper piping consistency of the potatoes.
To freeze the Duchess Potatoes, I pipe them on a baking sheet lined with parchment paper. Then, I put the piped Duchess Potatoes on the baking sheet in the freezer. Once they are frozen, I transfer the Duchess Potatoes to a Ziploc bag and place them in the freezer. To heat, I place the frozen Duchess Potatoes on a baking sheet and brush them with an egg wash. Then, I place them in a preheated 400°F oven for 35 minutes. If the Duchess Potatoes have thawed, then I bake them with the egg wash for 30 minutes in a preheated 400°F oven.
