Why it works: Pepper and tomato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Spanish Steak
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
Preheat the oven to 350°F (175°C).
Season the steak with salt and pepper, then rub with butter.
Place the steak in a sheet iron baking pan with water.
Bake and serve
Cook for 30 minutes.
Cover the steak with sliced onions and cook for an additional 45 minutes.
Add sliced tomatoes and cook until tender.
Sprinkle with grated cheese and bake until brown.
Serve with gravy made from the pan juices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Forms the main body of the dish and becomes tender with slow, moist cooking.
- Butter
- Adds fat that enriches flavor and helps the surface brown.
- Sliced onions
- Soften and sweeten as they cook over the steak, adding aroma.
- Sliced tomatoes
- Add moisture and acidity that mingle with the pan juices.
- Grated cheese
- Melts and browns on top, adding savory flavor and a golden crust.
The step that matters
Cook the steak in water before adding toppings. Steak this thick is tough and needs long, moist heat to break down connective tissue. Cooking it covered in liquid first keeps it from drying out before the browning step.
Swap the onion
