Why it works: Parsley and onion are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Blood or Veal Gravy
Ingredients
Directions
Prepare the base
In a thick stewpan, place a few slices of ham.
Layer slices of lean veal over the ham.
Half cover the meat with jelly stock and stew over a brisk fire, ensuring it does not burn.
Brown the meat
When the broth is reduced, insert a knife into the meat to let the gravy run out.
Stew gently until the meat is brown, turning it frequently.
When the meat is a dark red color, moisten it with hot stock.
Finish and clarify
Season with shredded mushrooms, parsley, and green onions.
After boiling for an hour, skim and strain the gravy through a tammy to clarify.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Slices of lean veal
- Provides the meat that cooks down and browns to flavor the gravy.
- Jelly stock
- Adds body and gelatin-rich liquid that reduces into a glossy, flavorful gravy.
- Slices of ham
- Lays a savory, salty base that enriches the flavor of the gravy.
- Hot stock
- Moistens the browned meat and extends the liquid to make the gravy.
- Shredded mushrooms
- Contributes earthy aroma and savory flavor to the finished gravy.
The step that matters
Stewing the meat until brown without burning. Browning the meat in a little liquid builds deep, savory flavor through caramelization, but too-high heat scorches the proteins and sugars and makes the gravy bitter. Gentle, frequent turning keeps the meat browned evenly.
Swap the parsley
How well each one fits the dish's main ingredients (ham, veal, mushroom, onion):
- Garlicfits better
- Thymefits better
- Celeryfits about as well
- Parsleythe original
Fit is the average pairing score against ham, veal, mushroom, onion. Candidates are from the same food group and used in at least 100 recipes.
