Lamb's Hearts, Fricasseed
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Soak the lamb's hearts in cold water.
Fill the cavities with veal stuffing and coat with flour.
Bake and stew
Bake in a moderate oven at 350°F (175°C) for 45 minutes.
Slice the hearts neatly.
Thicken the gravy.
Place the slices in a pan.
Stew gently for 15 minutes.
Serve
Arrange on a dish with fried tomato slices and chopped mushrooms.
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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb's hearts
- Form the main body of the dish, providing the meat that is sliced and stewed.
- Flour
- Coats the hearts and helps thicken the gravy as it cooks.
- Veal stuffing
- Fills the cavities, adding flavour and moisture to the hearts during baking.
The step that matters
Stew gently for 15 minutes. Gentle heat keeps the sliced meat tender and prevents the thickened gravy from scorching or boiling hard, which would toughen the meat and break the sauce.
Swap the tomato
How well each one fits the dish's main ingredients (lamb, veal, flour, mushroom):
- Shallotfits better
- Spinachfits better
- Asparagusfits better
- Tomatothe original
Fit is the average pairing score against lamb, veal, flour, mushroom. Candidates are from the same food group and used in at least 100 recipes.
