Irish Potatoes for Dinner or Luncheon

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. Peel and slice the potatoes into thin slices.

  2. Soak the slices in cold water for about 1 hour, changing the water 2-3 times.

  3. Boil the potatoes quickly until tender, then drain the water.

Make the mash

  1. Cream the potatoes in the same vessel using a silver fork.

  2. Add butter and salt, then mix in the milk until light and creamy.

  3. Fold in chopped parsley and celery.

Bake and serve

  1. Transfer to a baking dish, top with grated cheese and cracker crumbs, and dot with butter.

  2. Bake in a hot oven at 400°F (200°C) until browned.

  3. Garnish with parsley before serving hot.

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 casserole, giving a soft, starchy body once creamed.
Milk
Adds moisture and richness, loosening the mash into a creamy texture.
Butter
Adds fat for richness and flavour, and helps the top brown in the oven.
Cheese
Melts into the top layer and browns during baking, adding savoury flavour.
Cracker crumbs
Form a crisp, browned topping that contrasts with the creamy potato beneath.

The step that matters

Boil the potatoes quickly until tender. Potatoes that are overcooked or waterlogged turn gluey when creamed and hold too much water, so the mash becomes loose. Drain thoroughly and cook only until tender.

Swap the celery

How well each one fits the dish's main ingredients (potato, butter, milk, parsley, cheese):

  1. Thymefits better
  2. Dillfits about as well
  3. Nutmegfits about as well
  4. Celerythe original

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