Cream Potatoes

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Peel and boil the small potatoes until tender.

Make the cream sauce

  1. In a saucepan, melt the butter over medium heat.

  2. Stir in the flour and cook for 1 minute.

  3. Gradually add the boiling milk, stirring constantly until thickened.

  4. Season the sauce with coarse sea salt and pepper to taste.

Serve

  1. Pour the cream sauce over the boiled potatoes.

  2. Slice the hard boiled eggs and arrange them on top.

The flavor team

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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Small potatoes
Form the starchy base that the sauce coats.
Butter
Provides fat and richness, and carries the flour into the sauce.
Flour
Thickens the milk into a smooth sauce when cooked with the butter.
Milk
Forms the liquid of the sauce, which thickens as it heats.
Hard boiled eggs
Add soft texture and mild richness as a topping.

The step that matters

Gradually add the boiling milk, stirring constantly until thickened. Adding liquid too fast or without constant stirring lets the flour clump instead of dispersing evenly. Stirring keeps the starch granules separated so they swell and thicken the sauce smoothly.

Swap the potato

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

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

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