Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Sweetbreads in Brown Sauce
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 the sweetbreads
Soak the sweetbreads in salted water for a few hours, then wash well.
Boil the sweetbreads in water for 5 minutes, then place them in cold water for a few minutes.
Trim and remove skin, gristle, and fat; cut each sweetbread into 2 or 3 pieces.
Butter a small oven tin and place the sweetbreads in it, adding a small piece of butter on top of each.
Roast in the oven at 350°F (175°C) for about 20 minutes.
Make the brown sauce
In a saucepan, combine sugar and 1 oz butter; allow to brown.
Add the chopped onion and fry until brown.
Stir in the flour and fry until it begins to look yellow.
Add salt, pepper, cayenne, nutmeg, lemon juice, and water; stir until it boils for about 10 minutes.
Strain the sauce through a fine strainer and return it to the pan.
Combine and serve
Add the sweetbreads and mushrooms, cooking gently for about 30 minutes.
Serve with croutons of bread or pieces of pastry.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Main protein; the tender, delicate meat that is the body of the dish.
- Butter
- Adds richness and fat, and helps the sweetbreads brown in the oven.
- Flour
- Cooked in the butter to form a roux that thickens the sauce.
- Mushrooms
- Add earthy flavour and moisture to the finished sauce.
- Sugar
- Browns in the butter to add colour and a slight caramel sweetness to the sauce.
The step that matters
Browning the sugar and butter. Sugar left too long over heat turns bitter and dark, while too little browning leaves the sauce pale and flat. Watch closely and stop as it turns amber.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, mushroom, lemon, sugar, pepper):
- Shallotfits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against butter, flour, mushroom, lemon, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
