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 ↓
Spanish Steak
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 steak
Select a good sirloin or round steak at least 1½ inches thick.
Score the steak on both sides with a semi-sharp knife.
Spread soft butter on both sides of the steak, working it into the crevices.
Roll the steak in flour and place it in a covered baking dish or casserole.
Bake and top
Bake in a 350°F (175°C) oven for 20 to 30 minutes until half tender.
Add a little water if necessary, then layer finely chopped onions and celery over the steak.
Return to the oven and simmer until the onions are tender.
Season with salt and pepper, then spread a mixture of tomatoes, a little flour, and cayenne pepper over the steak.
Return to the oven and bake until the tomatoes are thick and lightly browned.
Serve
Serve hot on a chop plate garnished with parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sirloin or round steak
- Forms the main body of the dish and becomes tender through slow baking in the covered dish.
- Butter
- Adds fat and moisture that coats the steak and helps keep it from drying out.
- Flour
- Coats the steak and thickens the juices, helping form a light sauce around it.
- Onion
- Softens into the sauce, adding sweetness and savory depth to the juices.
- Tomatoes
- Add acidity and moisture, and thicken and brown on top for color and flavor.
The step that matters
Return to the oven and simmer until the onions are tender. Onions cook slowly in the juices and must soften fully; undercooked onions stay sharp and can taste raw. Keeping the dish covered retains moisture so the steak does not dry out.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, celery, tomato, pepper, parsley):
- Carrotfits better
- Okrafits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against butter, flour, celery, tomato, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
