Potato Rissoles

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Mash the potatoes until fine.

  2. Mix in butter, coarse sea salt, pepper, and a raw egg.

  3. Form the mixture into small cakes using a knife.

Bake

  1. Place the cakes on a buttered baking sheet.

  2. Beat the egg with cold water and brush it over the top of the cakes.

  3. Bake in a moderate oven at 350°F (175°C) until golden brown.

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

What each ingredient does

Potatoes
Form the body of the cakes, providing starch that holds them together as they bake.
Butter
Adds fat and richness, contributing flavour and a tender texture to the cakes.
Raw egg
Binds the mashed potato so the cakes hold their shape when formed.
Egg wash
Brushed on top to promote browning, giving the cakes a golden surface.

The step that matters

Brushing the top with egg wash. Egg proteins and sugars brown in the oven, so an even coat gives a golden finish. Thick or uneven coating can brown unevenly or look patchy.

Swap the potato

How well each one fits the dish's main ingredients (butter, pepper, egg):
