Mock Duck

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare the stuffing

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, mix the crumbled bread, chopped onion, pepper, salt, and melted butter.

  3. Spread the dressing over the steak.

Roll and bake

  1. Roll up the steak tightly and secure with kitchen twine or toothpicks.

  2. Place the rolled steak in a baking dish and bake for 1 hour or until cooked through.

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

What each ingredient does

Beef steak
Forms the outer meat that is rolled around the stuffing and cooks through in the oven.
Bread
Absorbs moisture and fat from the butter and onion, giving the stuffing a soft, tender body.
Onion
Adds moisture and savory sweetness as it softens in the stuffing during baking.
Butter
Adds fat that coats the bread crumbs, enriching flavor and keeping the stuffing moist.

The step that matters

Rolling the steak tightly. If the roll is loose, the stuffing can fall out and the steak may cook unevenly. A tight roll, secured well, holds the filling in place and keeps the layers together during baking.

Swap the onion

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

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