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 ↓
Peppers Stuffed with Sweetbreads
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
Simmer sweetbreads in boiling salted water with lemon juice for 5 minutes, then cut into small cubes.
Make the sauce
Melt butter in a pan, then stir in flour and cook for 1 minute.
Add chicken stock and cream, season with salt and pepper, and cook for 10 minutes.
Stir in sweetbreads and mushrooms if using.
Fill and bake
Fill the peppers with the mixture, top with buttered crumbs.
Bake at 350°F (175°C) until golden and serve on rounds of toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender, rich meat that forms the filling's main body.
- Butter
- Enriches the sauce and helps the flour cook into a smooth base.
- Flour
- Thickens the butter and stock into a smooth, stable sauce.
- Cream
- Adds richness and body, making the sauce silky and thicker.
- Chicken stock
- Forms the liquid base of the sauce and adds savoury flavour.
- Buttered crumbs
- Browns in the oven to give the topping a golden, crisp finish.
The step that matters
Cooking the flour in the butter. Cooking the flour for a full minute removes its raw starch taste before the liquid goes in, and lets it thicken the sauce smoothly without lumps.
Swap the lemon
How well each one fits the dish's main ingredients (butter, flour, chicken, cream, pepper, mushroom):
- Coconutfits about as well
- Lemonthe original
- Avocadofits about as well
- Mangofits less well
Fit is the average pairing score against butter, flour, chicken, cream, pepper, mushroom. Candidates are from the same food group and used in at least 100 recipes.
