Vegetable Marrow Au Gratin

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.

Prepare

  1. Half boil the marrows, then quarter them lengthwise and drain thoroughly.

  2. Rub a baking dish with a slice of shallot or garlic and butter it well.

Assemble and bake

  1. Place the marrows in the dish, sprinkle with Parmesan cheese, salt, pepper, and nutmeg.

  2. Dot with small pieces of butter and dust with bread crumbs.

  3. Bake at 400°F (200°C) for 20 minutes and serve hot in the original dish.

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

What each ingredient does

Vegetable marrows
Form the main body of the dish, becoming tender and moist as they cook.
Butter
Adds richness and helps the top brown while keeping the marrows from drying out.
Parmesan cheese
Melts and browns on top, adding savoury, nutty flavour and a golden crust.
Powdered baked bread crumbs
Form a dry topping that crisps and browns in the oven.

The step that matters

Drain the marrows thoroughly after boiling. Marrow holds a lot of water. Excess moisture left in the pieces will dilute the dish and make the topping soggy rather than golden.

Swap the shallot

How well each one fits the dish's main ingredients (butter, parmesan cheese, pepper, nutmeg, bread):

  1. Spinachfits better
  2. Capsicumfits better
  3. Asparagusfits about as well
  4. Shallotthe original

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