Why it works: Tomato and potato match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 2,797 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Put the oxtail, onion, carrots and tomato purée in a large pot, cover with water, bring to a boil, skim, then simmer gently for about 3 hours until the oxtail is tender. Strain, reserving the meat and the liquid.
Reduce the strained liquid by about two-thirds over medium heat. Stir in the redcurrant jelly and whisky, then add the cream and simmer until lightly thickened. Shred the oxtail meat into the jus and keep warm.
Halve the tomatoes' tops off, scoop out the seeds, and season the insides. Heat the haggis until it reaches 165°F (74°C) and spoon it into the tomatoes. Dot with butter and bake at 375°F (190°C) for about 15 minutes.
Thinly slice the red onion and cook in butter until soft. Shred the Savoy cabbage, blanch in a pan of boiling water for 2 minutes, drain, then toss with the onion, salt and pepper and keep warm.
Toss the julienned potatoes with the egg yolks, salt and pepper. Press into a buttered non-stick pan and cook over medium heat for about 5 minutes per side until golden and set, then keep warm.
Season the beef fillet steaks with salt and pepper. Heat olive oil in a heavy pan over high heat and sear the steaks for 2 minutes per side.
Transfer the steaks to a 400°F (200°C) oven and roast until the thickest part reaches at least 145°F (63°C), about 8 to 10 minutes. Rest for 3 minutes before slicing.
Serve the steak with the rosti, cabbage, haggis tomatoes and a spoonful of whisky jus.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
Flavor stand-ins for the carrot
How well each one fits the dish's main ingredients (onion, tomato, cream, whisky, beef, pepper, olive):
- Capsicumbetter flavor fit
- Potatobetter flavor fit
- Carrotthe original
- Spinachabout as good a flavor fit
Fit is the average pairing score against onion, tomato, cream, whisky, beef, pepper, olive. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
