Potato Cases

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

Preheat the oven to 400°F (200°C).

Shape the cases

In a bowl, combine the mashed potatoes and eggs; mix well.
Line small molds with the potato mixture.
Brush the molds with butter and sprinkle with fine bread crumbs.

Bake and fill

Bake until golden brown.
Fill with your choice of filling for patties.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mashed potatoes: Form the main body of the case and give it a soft, tender texture.
Eggs: Bind the potato mixture so it holds its shape when lined into molds.
Butter: Adds fat for browning and a richer flavour on the outside of the cases.
Fine bread crumbs: Create a crisp, golden crust on the outside of the cases.
