Both a hundred years ago and now, cooks sometimes struggle to figure out how to use leftovers. I recently had some leftover fish and some leftover mashed potatoes, so when I saw a recipe for Scalloped Fish in a 1924 cookbook that called for both cooked fish and mashed potatoes it seemed serendipitous, and I knew that I needed to give it a try.
The recipe was a winner. The Scalloped Fish was delightful, and I felt like I was being very frugal by using left-overs.
Here’s the original recipe:

I did not cook the milk mixture for the entire 20 minutes called for in the recipe. It seemed like it might begin to scorch on the bottom of the pan if I cooked it that long. I just cooked it until it came to a boil and thickened.
I added 1/2 teaspoon of salt and 1/4 teaspoon of pepper when I made this recipe.
Here’s the recipe updated for modern cooks:
Scalloped Fish
2 hard-boiled eggs
2 cups milk
2 tablespoons cornstarch
1 tablespoon butter + additional butter for topping
1/2 teaspoon salt
1/4 teaspoon pepper
2 cups cooked or canned fish, flaked (I used flounder.)
1/2 cup mashed potatoes
1 cup fine bread crumbs (I grated a slice of bread.)
Preheat oven to 400° F. Cut hard-boiled eggs in half. Mash the yolks with a fork. Press the whites through a sieve. (I used a Foley mill.) Set aside.
Put the cornstarch and 1/4 cup milk into a small bowl; stir until smooth. Put the milk mixture into a saucepan, then add the remaining 1 3/4 cups milk and stir together. Add 1 tablespoon butter. Bring to a boil using medium heat while stirring constantly. Reduce heat and gently simmer until the liquid thickens. Stir in the mashed egg yolks and egg whites that have been put through a sieve. Remove from the heat and add the flaked fish and the mashed potatoes; stir until combined. Put in a baking dish. Sprinkle the bread crumbs on top and dot with small pieces of butter. Bake in oven until hot and bubbly (approximately 15-25 minutes).
