To Cook 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.

Chop the cold meat finely in a bowl.
Season with salt, pepper, and either onion or tomato ketchup.
Fill a tin bread pan two-thirds full with the mixture.
Top with salted mashed potatoes mixed with milk.
Dot with bits of butter and bake in a 400°F (200°C) oven for 15-20 minutes.

Recipe from a historical cookbook (Internet Archive).

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.
