Why This Recipe is Seed Oil Free

Instructions
Step 1. Wash and peel 1800g organic russet potatoes, then cut into uniform 2-inch chunks. Place in a large pot and cover completely with cold water plus 1 inch. Add 1 teaspoon salt to the water. This ensures even cooking and prevents the outside from becoming mushy before the centers are done.
Step 2. Bring to a rolling boil over high heat, then reduce to medium-high and cook for 15-20 minutes until fork-tender throughout. Test doneness by piercing the largest chunk - it should slide off the fork easily. Overcooked potatoes will become gummy when mashed.
Step 3. Drain potatoes thoroughly in a colander and let them steam-dry for 2-3 minutes. This removes excess moisture that would make the mixture too wet to pipe. While still very hot, pass potatoes through a potato ricer or food mill into a large mixing bowl. Never use a regular masher or food processor as these create a gluey texture.
Step 4. Immediately add 170g room-temperature organic butter, 4 egg yolks, 2 teaspoons onion powder, 1.5 teaspoons sea salt, and 60ml heavy cream. Using a wooden spoon or stand mixer with paddle attachment, beat vigorously for 2-3 minutes until completely smooth and fluffy. The mixture should hold its shape when piped but not be stiff - add 1-2 tablespoons more cream if needed.
Step 5. Preheat oven to 425°F (220°C). Line two large baking sheets with parchment paper. Transfer potato mixture to a large pastry bag fitted with a star tip (or use a large zip-lock bag with corner cut off). Pipe 2-inch rosettes or spiral mounds onto prepared sheets, spacing them 1 inch apart. You should get about 100 pieces total.
Step 6. Bake for 12-15 minutes until tops and edges are golden brown. The bottoms should be lightly golden and crispy. Let cool for 2-3 minutes before serving. These are best served immediately while crispy outside and fluffy inside. To reheat leftovers, bake at 400°F for 5-7 minutes until re-crisped.
Storage
Store cooled duchess potatoes covered in refrigerator for up to 3 days. Reheat in 400°F oven for 5-7 minutes to restore crispiness. Can be frozen for up to 1 month - freeze on baking sheets first, then transfer to bags.
