Potato Cheese-cakes

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the filling

  1. Grate the thin rind of the lemons.

  2. Pound the lemon rind with the sugar and boiled potato until well combined.

  3. Stir in the clarified butter until smooth.

  4. Add the egg yolks and egg white, mixing well.

Bake

  1. Line tart tins with the light crust and fill them more than halfway.

  2. Bake in a 400°F (200°C) oven for about 20 minutes.

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

What each ingredient does

Boiled potato
Adds body and moisture, giving the filling a soft, tender texture.
Clarified butter
Adds fat for richness and a smooth, silky texture in the filling.
Egg yolks
Enrich the filling and help it set into a custard-like texture when baked.
Egg white
Adds structure and helps the filling set as it bakes.
Sugar
Adds sweetness and helps brown the surface of the cakes.
Lemons
Rind adds bright citrus aroma and a touch of acidity.

The step that matters

Pound the potato until fully combined. Lumps of potato or unmixed sugar leave an uneven texture, so the rind, sugar and potato should be worked together until smooth before the butter and eggs go in.

Swap the potato

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