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 a LA Princesse
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the sweetbread
Prepare the sweetbread as for "Sweetbread à la Italienne".
Place it in a stew pan with the velouté sauce and mushroom trimmings.
Simmer gently until tender, about 1 to 1.5 hours.
Make the sauce
Combine the egg yolks and cream with the sauce.
Thicken the mixture without boiling.
Prepare the tomatoes and serve
Transfer the sweetbread onto the fried bread.
Pour the sauce over the sweetbread.
Cut the tomatoes in half. Scoop out some pulp. Season the tomatoes.
Bake the tomatoes in a 350°F (175°C) oven.
Fill the tomatoes with heated peas.
Arrange the tomatoes at each end of the sweetbread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbread
- Forms the tender main body of the dish, becoming soft and delicate when simmered gently.
- Egg yolks
- Thicken the sauce as they gently set with heat, giving it a smooth, rich body.
- Cream
- Adds richness and moisture, softening the sauce's texture and flavour.
- Velouté sauce
- Provides the base sauce that carries flavour and coats the sweetbread.
The step that matters
Thicken the mixture without boiling. Egg yolks scramble and curdle if they get too hot, so the sauce must be thickened gently to stay smooth and creamy.
Swap the lemon
How well each one fits the dish's main ingredients (sauce, egg, cream, pepper, mushroom, bread, tomato):
