Boil and steam

  1. Boil the potatoes in a kettle of boiling water until easily pierced with a fork.

  2. Drain the water and set the kettle on the back of the stove. Cover and let the potatoes steam for about 5 minutes.

  2. Serve with Drawn Butter Sauce.

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 flesh that becomes soft and tender when boiled and steamed.
Butter
Adds richness and moisture to the sliced potatoes.

The step that matters

Boil until easily pierced with a fork. Sweet potatoes must be fully cooked through so the starch softens evenly. Underdone centers stay firm and grainy, while the potatoes can break apart if overcooked.

Swap the sweet potato

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