Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb's sweetbreads
- Provide the tender, delicate meat that forms the body of the dish.
- Butter
- Fat for frying, which browns the sweetbreads and adds rich flavor.
- Flour
- Thickens the cream into a sauce that coats the sweetbreads.
- Boiling cream
- Forms the rich sauce, adding moisture and a smooth, creamy texture.
- Egg yolks
- Enrich and thicken the sauce, giving it body and a smooth finish.
- Mushrooms
- Add moisture and earthy flavor that complements the sweetbreads and cream.
The step that matters
Adding the egg yolks. Egg yolks thicken when heated, but if the sauce is too hot they can scramble and turn grainy. Mixing them with a little warm sauce first, then adding gradually, tempers them so the sauce stays smooth.
