To Warm Cold Meats

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

Preheat the oven to 400°F (200°C).
Chop the cold meat finely and mix with salt, pepper, onion, and tomato ketchup.
Fill a baking dish one-third full with the meat mixture.

Bake and serve

Top with mashed potatoes and dot with butter.
Bake for 15 to 20 minutes until heated through.

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

What each ingredient does

Cold meat: Forms the main filling and provides the savory body of the dish.
Boiled potatoes: Form a soft topping that insulates the meat and browns in the oven.
Butter: Adds richness and helps the potato topping brown as it bakes.
Tomato ketchup: Adds sweetness and acidity while adding moisture to the meat mixture.
