Potato Souffle

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.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the mixture

  1. In a bowl, combine the mashed potatoes, melted butter, and salt until smooth.

  2. Add the cream and the eggs (beaten separately) to the potato mixture. Mix everything together until well combined.

Bake

  1. Pour the mixture into a baking dish and bake until nicely browned.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Mashed potatoes
Form the bulk of the dish, giving it a soft, light body.
Eggs
Set the mixture as it bakes, giving the souffle structure and lift.
Cream
Adds moisture and richness, keeping the interior tender.
Melted butter
Adds fat for richness and smoothness, and helps browning on the surface.

The step that matters

Baking until nicely browned. Baking until the surface is nicely browned sets the eggs and dries the top, so the souffle holds its shape. Underbaking leaves it wet and slack, while the browning comes from the Maillard reaction on the surface.

Swap the potato

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

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

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