Caramel Sweet Potatoes

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Boil sweet potatoes until tender, allowing water to reduce to 2 tablespoons.

  2. Remove potatoes and add light brown sugar to the water to make a syrup.

Bake and serve

  1. Add butter to the syrup and pour it over the potatoes in a baking dish.

  2. Bake for 30 minutes at 350°F (175°C).

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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, tender base that soaks up the syrup.
Light brown sugar
Dissolves into the water to form a syrup that caramelizes and sweetens the potatoes.
Butter
Adds fat and richness, helping the syrup become glossy and smooth.

The step that matters

Reducing the water to 2 tablespoons. If too much water remains, the syrup stays thin and will not caramelize. If it reduces too far, the sugar can scorch. Watching the volume keeps the syrup at the right concentration for a glossy glaze.

Swap the sweet potato

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

  1. Sweet potatothe original
  2. Leekfits about as well
  3. Potatofits about as well
  4. Capsicumfits less well

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