Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Sweetbread Croquettes
Ingredients
Directions
Prepare the sweetbreads
Blanch the sweetbreads in boiling water with salt, lemon juice, bay leaf, onion, and celery for 20 minutes.
Remove the sweetbreads from the water and cover them with cold water.
Once cold, pick apart the sweetbreads, discarding as much membrane as possible.
Make the filling
Melt butter in a saucepan, add flour and mix well.
Stir in cream or milk until it bubbles.
Add seasonings and the egg yolk, and cook for a moment longer.
Pour the mixture over the sweetbreads and mix well.
Let the mixture cool completely.
Mold the cooled mixture as desired.
Coat, fry and serve
Roll the molded mixture in fine bread crumbs.
Dip the crumb-coated mixture in egg mixed with hot water.
Roll the mixture in coarse bread crumbs.
Fry two croquettes at a time in hot fat until golden.
Drain the fried croquettes on paper.
Serve the croquettes with cream sauce and mushrooms.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Form the main body of the croquettes, providing the meaty filling texture.
- Flour
- Thickens the melted butter and cream into a binding sauce that holds the filling together.
- Cream or milk
- Adds moisture and richness, setting into a smooth, cohesive filling once cooled.
- Egg
- Binds the filling and, as a wash, helps the bread crumbs adhere to the surface.
- Butter
- Adds fat and flavor to the roux base that thickens the filling.
The step that matters
Let the mixture cool completely before molding. Warm filling is soft and sticky, so it will not hold its shape or stay coated. Once cooled, the starch-thickened sauce firms up, letting the croquettes keep their form through breading and frying.
Swap the onion
How well each one fits the dish's main ingredients (egg, cream, butter, flour, parsley, nutmeg, lemon):
- Shallotfits better
- Arrowrootfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against egg, cream, butter, flour, parsley, nutmeg, lemon. Candidates are from the same food group and used in at least 100 recipes.
