Lamb Sweetbreads, Larded
Ingredients
Directions
Prepare the sweetbreads
Soak the sweetbreads in water for 2–3 hours, changing the water frequently.
Boil the sweetbreads in a saucepan for 5–6 minutes to firm them up.
Remove the sweetbreads and place them in cold water.
Lard the sweetbreads closely.
Make the sauce
In a stewpan, combine the larded sweetbreads with veal stock, carrot, onion, celery, and butter rolled in flour.
Simmer gently for 10 minutes, basting liberally.
Beat the egg and mix it with cream, parsley, and nutmeg.
Remove the carrot, onion, and celery from the sauce.
Let the sauce cool for a minute.
Add the egg and cream mixture to the sauce.
Stir constantly until hot, but do not let it boil.
Season with salt and pepper if needed.
Serve
Serve the sweetbreads on a hot dish, strain the sauce over them, and serve with sorrel or tomato sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Main protein; firming in boiling sets their texture before larding and simmering.
- Egg
- Thickens the cream sauce as it gently heats, giving it body without boiling.
- Cream
- Adds richness and smoothness to the sauce, helping it coat the sweetbreads.
- Butter
- Rolled in flour, it thickens the veal stock into a light sauce.
- Veal stock
- Forms the savoury base of the sauce and carries the flavour of the vegetables.
The step that matters
Stir the egg and cream mixture in off the heat, and do not let it boil. Egg proteins set and curdle when overheated, so the sauce turns grainy. Cooling briefly and stirring constantly keeps it smooth and thickened.
Swap the onion
How well each one fits the dish's main ingredients (veal, carrot, celery, butter, flour, egg, cream):
- Leekfits better
- Parsnipfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against veal, carrot, celery, butter, flour, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
