My German grandmother made the best mashed potatoes. This creamy texture is taken to the next level with the addition of poached lobster meat.

Mashed Potatoes ingredients

10 medium to large Yukon potatoes, peeled and diced
3 bay leaves
1 pound butter
1 cup heavy cream, hot
6 ounces soft herbed cheese (Recommended: Boursin)
4 ounces sour cream
Salt and white pepper to taste

Buerre Fondue ingredients

1 quart chicken stock
4 garlic cloves
1 teaspoon black peppercorns
3 sprigs of thyme
2 pounds butter, diced and kept cold
1 pound lobster meat, diced
1/4 cup chopped fresh chives
Salt and white pepper to taste


Mashed Potatoes


Boil the potatoes with the bay leaves until the potatoes are tender. Drain the potatoes well and discard the bay leaves. Mash the potatoes using a food mill and add the butter, hot cream, salt, and white pepper. Fold in the boursin cheese and sour cream, allowing it to melt into the potatoes and set aside in a warm place.

Buerre Fondue


Combine all ingredients, except the butter. Bring to a simmer and reduce by 2/3. Turn down the heat and start adding the cold butter, whisking constantly to emulsify. Adjust seasoning with salt and white pepper. Strain through chinois.


To finish, gently poach the diced lobster in the buerre fondue. Place the poached lobster on top of the boursin mashed potatoes. Sauce with some more buerre fondue. Garnish with chives.
