Why it works: Tarragon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,563 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Spanish Steaks
Ingredients
Directions
Prepare the steaks
Cut the steak into rounds and score them with a knife.
Sprinkle parsley on top of each round, then drizzle with melted butter and vinegar.
Fry the onion
Let the steak marinate while frying the sliced onion in beef dripping.
Strain the onions and ensure no dripping remains in the pan.
Simmer and serve
Cover the bottom of the pan with hot stock and gently simmer the steaks for one hour.
Remove the lid and boil the gravy until reduced to about ¾ cup.
Pour the gravy around the steaks and garnish with parsley, adding the onions just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump steak
- Forms the main meat, which becomes tender through long, gentle simmering.
- Onion
- Frying softens it and brings sweetness and aroma to the gravy.
- Beef dripping
- Adds fat and savory flavor, and helps the onion brown while frying.
- Brown stock
- Provides the cooking liquid that becomes the gravy, adding savory depth.
- Melted butter
- Adds richness and a smooth, rounded flavor to the steaks.
- Tarragon vinegar
- Adds acidity and a sharp, herbal note that brightens the rich meat.
The step that matters
Simmer the steaks gently for one hour. A gentle simmer lets connective tissue in tougher cuts break down slowly and keeps the meat tender. A hard boil tightens the muscle fibres and toughens the steak, and it can also reduce the liquid too quickly.
