Ingredients

Directions

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

Make the potato mixture

  1. Add butter, salt, and beaten yolks to the potatoes.

  2. Beat until very light.

Shape and bake

  1. Put the mixture in a pastry bag with a large rose tube.

  2. Shape on a buttered baking sheet.

  3. Brown lightly in a 400°F (200°C) oven.

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

What each ingredient does

Riced potatoes
Form the bulk of the mixture, giving a soft, light base that holds its shape.
Butter
Adds richness and moisture, softening the texture of the potatoes.
Egg yolks
Add richness and help bind the mixture so it holds its piped shape.

The step that matters

Beat until very light. Beating incorporates air and smooths the mixture so it pipes cleanly into roses. Under-beaten potato stays dense and may clog or crack the pastry bag tip, while the shape keeps its definition better when the mixture is well aerated and evenly combined.

Swap the potato

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

  1. Asparagusfits better
  2. Chivefits better
  3. Leekfits about as well
  4. Potatothe original

Fit is the average pairing score against butter, egg. Candidates are from the same food group and used in at least 100 recipes.
