Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the stuffing
Pound the steak on both sides.
Chop the bread, potatoes, celery, onion, and parsley very fine.
Add the egg and butter to the chopped mixture, and season with pepper and salt.
Roll and bake
Spread the stuffing over the steak, roll it up, and tie it securely.
Place the rolled steak in a roasting pan, add a little water, and bake in a 350°F (175°C) oven.
Baste often and bake until tender.
Serve
Remove the meat to a platter and thicken the gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Forms the outer wrap that cooks up tender around the stuffing.
- Bread
- Absorbs moisture and gives the stuffing body and structure.
- Potatoes
- Add starch and bulk to the stuffing, helping it hold together.
- Egg
- Binds the chopped stuffing ingredients together as it sets during cooking.
- Butter
- Adds fat and richness to the stuffing and helps keep it moist.
The step that matters
Baste often and bake until tender. Round steak is a lean, tough cut that needs long, moist cooking to break down its connective tissue. Basting keeps the surface from drying out while the collagen slowly softens into tender meat.

Fit is the average pairing score against bread, potato, celery, parsley, egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
