Why it works: Parsley and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
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
Soak sweetbreads in cold salted water to cleanse and remove blood.
Blanch sweetbreads in cold water with vinegar or lemon juice, peppercorns, parsley, and onion. Bring the mixture to a boil.
Lift out the sweetbreads and press them between two plates until cold.
Wrap the sweetbreads in bacon and then wrap the bacon-wrapped sweetbreads in buttered paper.
Braise
Place the wrapped sweetbreads in a stew-pan with butter, carrot, onion, celery, and herbs. Fry lightly for 12–15 minutes.
Pour in stock.
Cook gently in the oven at 350°F (175°C) for 1 hour, adding more stock as needed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Main protein; becomes tender and delicate when gently cooked in liquid and fat.
- Butter
- Adds richness and helps lightly brown the vegetables and sweetbreads during the initial frying.
- Stock
- Provides moisture for gentle braising so the sweetbreads do not dry out in the oven.
- Bacon
- Adds fat and savory flavor, basting the sweetbreads as they cook.
The step that matters
Pressing the sweetbreads until cold. Pressing firms the cooled sweetbreads so they hold their shape and wrap neatly. Letting them cool fully before wrapping also keeps the bacon and paper from becoming greasy and loose.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, parsley, butter, carrot, celery):
- Parsnipfits better
- Turnipfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against vinegar, parsley, butter, carrot, celery. Candidates are from the same food group and used in at least 100 recipes.
