Escaloped Sweet Potatoes

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.

Assemble

  1. Layer cold boiled sweet potatoes on a platter.

  2. Cover with white sauce.

  3. Add another layer of potatoes and more sauce.

  4. Top with soft white bread crumbs and drizzle with melted butter.

Bake

  1. Bake at 400°F (200°C) until the crumbs are brown.

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
Form the bulk of the dish and give it a soft, tender body.
White sauce
Adds moisture and creaminess that keeps the potatoes from drying out in the oven.
Soft white bread crumbs
Form a top layer that browns in the oven, adding color and a crisp contrast.
Melted butter
Adds fat that helps the crumbs brown evenly and adds richness.

The step that matters

Bake until the crumbs are brown. The crumbs need enough heat for browning, which depends on dry surface sugars and proteins reacting at high temperature. Pulling the dish too early leaves the top pale and the interior underheated, while overbaking can dry out the sauce.

Swap the sweet potato

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

  1. Shallotfits better
  2. Tomatofits better
  3. Capsicumfits better
  4. Sweet potatothe original

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