Hashed and Browned 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 the potatoes

  1. Pare and cut the potatoes into very small, even pieces.

  2. Place the potatoes in a saucepan with the minced onion and chopped celery.

  3. Cover with salted boiling water and cook until tender.

Make the sauce

  1. Drain the water and add the heated milk with a pinch of baking soda.

  2. Bring to a bubble and stir in the butter, rubbed to a cream with the flour.

  3. Season with pepper and salt, mixing well without breaking the potatoes.

  4. Remove from heat, stir gently, and transfer to a greased pudding dish.

Bake and serve

  1. Sprinkle bread crumbs on top and brown 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

Potatoes
Form the bulk of the dish and set its soft, tender body when cooked.
Milk
Adds moisture and creaminess to the potatoes, forming a smooth binding liquid.
Butter
Adds richness and fat, carrying flavour and giving a smooth mouthfeel.
Flour
Thickens the butter and milk mixture so it holds together rather than running.
Bread crumbs
Form a topping that browns in the oven, adding a crisp golden surface.

The step that matters

Stir gently after adding the milk and butter. Cooked potatoes are fragile; vigorous stirring breaks their starch-rich cells, releasing starch and turning the dish gluey and mushy instead of light and pieces-intact.

Swap the celery

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

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

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