Beefsteak Pie
Ingredients
Directions
Flatten the steaks and season with mixed spices, salt, and pepper.
Layer the seasoned steaks in the bottom of a baking dish.
Add bits of boiled onion and fresh butter over the steaks.
Fill the dish two-thirds full, sprinkling onion between each layer of meat.
Pour 1 pint of boiling water seasoned with walnut ketchup over the meat.
Let the dish cool, then cover it with pastry, ensuring to create an ornamented top.
Make a center ornament to allow for adding more liquid if needed before serving.
