- 200 g White Beans (canned or cooked, any white bean, lentils or other pulse)

Instructions
Slice the potatoes
Peel the potatoes and run them through a mandolin set to the thinnest setting (about 1 mm). Collect the slices in a large bowl.
Time: PT15M
Melt the duck fat
Place the duck fat in a saucepan over medium heat and melt until fully liquid.
Time: PT5M
Temperature: medium heat
Coat the potato slices
Pour the melted duck fat over the potato slices and toss gently until every slice is evenly coated.
Time: PT5M
Prepare the baking tin
Line the baking tin with a sheet of parchment paper.
Time: PT2M
Layer the potatoes
Lay a single layer of coated potato slices on the parchment, dust lightly with corn flour, and sprinkle a handful of white beans. Repeat the process, building up thin layers until the tin is full, making sure there are no gaps.
Time: PT10M
Press and cover
Place another piece of parchment on top of the stacked layers and press down with a second tray or a cast‑iron lid to keep the potatoes tightly packed.
Time: PT2M
Bake the terrine
Preheat the oven to 180°C (350°F). Bake the pressed terrine for 2 hours, covered with foil if the top browns too quickly.
Time: PT2H
Temperature: 180°C
Cool and chill
Allow the terrine to cool to room temperature (about 30 minutes), then cover and refrigerate overnight to set.
Time: PT30M
Unmold and slice
Remove the terrine from the tin, invert onto a cutting board, peel away the parchment, and cut into 1.5‑cm thick slices using a serrated knife.
Time: PT15M
Fry the slices
Heat butter and oil in a skillet over medium‑high heat. Fry the potato slices, turning once, until both sides are golden‑brown and crisp, about 2‑3 minutes per side.
Time: PT15M
Temperature: medium‑high
Season and serve
Season the fried slices with salt and freshly ground black pepper. Serve hot as a side dish or snack.

Critical Steps — Do Not Skip
- Coating every potato slice with duck fat
- Building the layers without gaps
- Pressing the terrine firmly before baking
- Baking for the full 2 hours at 180°C
- Chilling overnight for proper set
- Slicing the chilled terrine cleanly
- Frying until golden without burning
Chef Tips from the Video
- Use starchy Russet potatoes for the best texture.
- A light dusting of corn flour acts like glue between layers.
- Pressing with a heavy cast‑iron lid creates a uniform shape and prevents air pockets.
- Fry the slices just until golden; over‑cooking makes them hard.
Troubleshooting
Slices fall apart when cutting.
Ensure the terrine has chilled for at least 8 hours; if still fragile, press it with a weight for an additional 30 minutes before refrigerating.
Terrine is soggy after baking.
Make sure each layer is dusted with corn flour and that the duck fat coating is not excessive. Baking at 180°C for the full 2 hours is essential.
Fried slices are greasy.
Drain the fried slices on paper towels and blot gently. Use a 1:1 butter‑oil mix to reduce splatter and absorb excess fat.
Storage
Refrigerator: Store leftover fried slices in an airtight container for up to 3 days.
Freezer: Unfried terrine can be wrapped tightly and frozen for up to 1 month; thaw before slicing and frying.
Room temperature: Do not store at room temperature; the high fat content can spoil.
Make-Ahead Tips
- The terrine can be baked and chilled up to 2 days in advance; keep covered.
- Slices can be frozen after frying and reheated in a hot oven for crispness.
Frequently Asked Questions
What is the cultural significance and history of Potato Milk (Layered Duck‑Fat Potato Terrine) in French cuisine?
The layered potato terrine, sometimes called "pommes de terre en terrine," dates back to classic French haute cuisine where thinly sliced vegetables were bound with fat to create elegant, sliceable molds. It showcases the French love of technique, texture contrast, and the use of rich animal fats like duck fat.
What are the traditional regional variations of this potato terrine in French cuisine?
In the southwest of France, duck fat is traditional, while in the north butter or cream may be used. Some regions add herbs such as thyme or rosemary, and others incorporate cheese layers like Gruyère for extra richness.
How is Potato Milk traditionally served in France?
It is typically served cold, sliced and then pan‑fried just before the meal, accompanied by a simple green salad or a light vinaigrette. It can also appear as a refined appetizer on a tasting menu.

The dish combines the buttery richness of duck fat with the delicate texture of paper‑thin potato sheets, creating a contrast of crisp exterior and melt‑in‑your‑mouth interior that epitomizes French technique‑driven comfort food.
What are the most common mistakes to avoid when making Potato Milk at home?
Common errors include uneven potato slices, insufficient duck‑fat coating, skipping the corn‑flour dusting, and not chilling the terrine long enough. Each of these leads to a crumbly or soggy final product.
Why does this recipe use duck fat instead of butter for binding the potato layers?
Duck fat has a higher smoke point and a richer, more gelatinous texture than butter, which helps the thin potato sheets adhere firmly during baking and creates a luxurious mouthfeel when fried.

Yes, bake the terrine, let it cool, then refrigerate it covered for up to three days. For longer storage, wrap it tightly and freeze; thaw before slicing and frying.

The terrine should be firm to the touch, with a deep golden‑brown top and no liquid pooling. The layers should be clearly defined and hold together when lifted.
How do I know when the fried potato slices are finished?
The slices are ready when they turn a deep golden‑brown, are crisp on the outside, and the interior feels soft and slightly molten. They should release easily from the pan without sticking.
