Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Sweetbreads a LA Creme
Ingredients
Directions
Prepare the sweetbreads
Soak the sweetbreads in cold water, then bring to a boil and cook for 3 minutes.
Trim away all the fat from the sweetbreads.
Simmer
In a pan, combine the sweetbreads with milk, stock, lemon rind, onion, mace, salt, pepper, parsley, and peppercorns.
Simmer gently for 45 minutes.
Make the cream sauce
In another pan, melt the butter and stir in the flour.
Gradually pour in the stock and milk mixture, stirring until well combined.
Add the cream and bring to a boil.
Stir in the sweetbreads and a squeeze of lemon juice.
Serve garnished with truffles and parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender, delicate meat that forms the body of the dish.
- Butter
- Melts with the flour to form the base of the roux that thickens the sauce.
- Flour
- Thickens the sauce when cooked with butter and combined with the liquid.
- Cream
- Adds richness and a smooth, velvety texture to the sauce.
- Milk
- Forms the liquid base of the sauce, adding body and mild sweetness.
- Stock
- Adds savoury depth to the sauce liquid.
The step that matters
Make the roux and add the liquid gradually. Cooking the butter and flour together before adding liquid gives a smooth sauce. Pouring the liquid in slowly while stirring prevents lumps, because starch granules need to disperse evenly before they thicken.
Swap the mace
How well each one fits the dish's main ingredients (lemon, onion, pepper, parsley, milk, butter, flour):
- Thymefits better
- Marjoramfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against lemon, onion, pepper, parsley, milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
