Sweet Potatoes

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.

Boil and bake

  1. Wash the sweet potatoes.

  2. Place them in a kettle of boiling water and boil for 20 minutes.

  3. Remove the potatoes and place them in a baking dish.

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

Steam as an alternative

  1. Alternatively, peel and slice the sweet potatoes.

  2. Place them in a saucepan with a bit of butter.

  3. Sprinkle with coarse sea salt.

  4. Barely cover the potatoes with water.

  5. Cover the saucepan tightly to steam them quickly.

Finish and serve

  1. When the potatoes are soft throughout, add sweet cream or a little more butter.

  2. Mash lightly before serving.

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

What each ingredient does

Sweet potatoes
Provide the starchy body of the dish, which softens and becomes creamy when fully cooked.
Butter
Adds fat for richness and a smooth texture, and helps carry flavor.
Sweet cream
Adds richness and moisture to the mashed potatoes, making them smoother.

The step that matters

Cook until soft throughout. Starch in the potatoes only becomes tender and creamy when heated through to the center. Stopping early leaves dense, grainy patches that stay firm when mashed, so test that the middle is soft before adding cream or butter.

Swap the sweet potato

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

  1. Potatofits better
  2. Onionfits better
  3. Leekfits better
  4. Sweet potatothe original

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