Annas Potatoes

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

  1. Slice the potatoes very thin and place them in a baking dish.

  2. Sprinkle with salt and pepper.

  3. Add the chopped onion.

  4. Pour enough sweet cream over the potatoes and add a good-sized lump of butter.

Bake and serve

  1. Bake in a 400°F (200°C) oven until well done.

  2. Serve in a dish and garnish with celery tops.

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

What each ingredient does

Potatoes
Form the bulk of the dish and soften into tender layers as they bake.
Sweet cream
Adds moisture and richness, turning into a silky sauce that coats the potato slices.
Butter
Adds fat and richness, helping the top brown and the flavor develop.
Onion
Adds savory aroma and sweetness as it cooks in the cream and butter.

The step that matters

Slicing the potatoes very thin. Thin slices cook through evenly within the baking time and release starch that thickens the cream into a sauce. Thick slices can stay firm in the centre while the outside overbakes.

Swap the celery

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

  1. Garlicfits better
  2. Parsleyfits about as well
  3. Thymefits about as well
  4. Celerythe original

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