Why it works: Pepper and lemon 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 ↓
Scalloped Sweetbreads
Ingredients
Directions
Prepare the sweetbreads
Soak the sweetbreads in salt water, changing the water 2 or 3 times.
Wash and clean the sweetbreads thoroughly.
Place the sweetbreads in an enamelled pan with enough cold water to cover, and bring to a boil.
Remove the sweetbreads from the boiling water, wash them, and return them to the pan with enough stock to cover.
Simmer gently until tender, about 1 to 2 hours.
Remove the sweetbreads from the stock and place them in cold water for a few minutes to firm up.
Dry, trim, and slice the sweetbreads about ½ inch thick.
Make the sauce
In a pan, combine the butter and flour over medium heat, rubbing together with a wooden spoon until smooth.
Gradually add the stock, stirring continuously until it boils and thickens.
Boil well, then add the cream and cayenne pepper.
Reheat the sauce if too thick, adding more cream if necessary.
Set aside the remaining sauce to serve with the sweetbreads.
Coat, fry and serve
Lay the sweetbread slices on a plate and cover with part of the sauce, turning to coat both sides.
Let them sit until firm.
Brush the sweetbreads with egg and coat in breadcrumbs.
Fry the sweetbreads in hot fat until golden brown, then drain on paper.
Serve the sweetbreads in a circle with sauce around and peas, French beans, or mushrooms in the center.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Main ingredient; simmering in stock makes them tender before coating and frying.
- Flour
- Thickens the butter-based roux that forms the sauce.
- Butter
- Fat that combines with flour to form the roux, adding richness to the sauce.
- White stock
- Liquid that becomes the sauce body and cooks the sweetbreads to tenderness.
- Cream
- Adds richness and smoothness to the sauce.
The step that matters
Simmer gently until tender. Boiling vigorously toughens the delicate sweetbread membranes and can break the meat apart, so a gentle simmer keeps them tender and intact.
