A Nice Way of Cooking 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
Chop the cold cooked meat finely.
Season with coarse sea salt, black pepper, and either onion or tomato ketchup.
Assemble
Fill a bread pan two-thirds full with the meat mixture.
Top with salted mashed potatoes mixed with milk.
Dot the top with bits of butter.
Bake
Bake in a 400°F (200°C) oven for 15 to 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold cooked meat
- Forms the main filling and provides the savoury base of the casserole.
- Mashed potatoes
- Forms a soft topping that browns in the oven and keeps the meat moist below.
- Butter
- Melts over the potato topping, adding richness and helping it brown.
- Milk
- Loosens the mashed potatoes so they spread easily and stay soft when baked.
