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 ↓
Sweetbread in Cases
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Cut the cooked sweetbread into dice.
Make the sauce
Simmer the mushrooms in butter until tender.
Stir in the flour and cook for 1 minute.
Add the milk gradually, stirring until thickened.
Remove from heat and mix in the egg yolk, lemon juice, pepper, and salt.
Fold in the diced sweetbread and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked sweetbread
- Forms the main body of the filling and supplies the rich, tender texture.
- Butter
- Fat that softens the mushrooms and adds richness to the sauce.
- Flour
- Thickens the butter and milk into a smooth white sauce.
- Milk
- Liquid that, heated with the flour, forms the body of the sauce.
- Egg yolk
- Enriches the sauce and adds richness and body when stirred in off the heat.
- Lemon juice
- Adds acidity that brightens the richness of the sauce.
The step that matters
Add the egg yolk off the heat. Egg yolk can scramble if it meets high heat. Removing the sauce from the heat before stirring it in lets the yolk thicken it smoothly.
Swap the lemon
How well each one fits the dish's main ingredients (mushroom, butter, flour, milk, egg, pepper):
- Lemonthe original
- Figfits about as well
- Coconutfits less well
- Plumfits less well
Fit is the average pairing score against mushroom, butter, flour, milk, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
