Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare and brown
Beat the beefsteaks lightly with a rolling pin, then season with flour, coarse sea salt, and black pepper.
Fry the seasoned steaks with the sliced onion until browned.
Stew and finish
Place the steaks in a stewpan and pour enough boiling water over them to create a sauce.
Stew gently for about 30 minutes.
Add ketchup before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beefsteaks
- The main protein, providing the meaty body and savoury flavour of the dish.
- Flour
- Coats the steaks so they brown well and helps thicken the sauce.
- Onion
- Softens and sweetens as it fries, adding aroma and depth to the sauce.
- Ketchup
- Adds sweetness, acidity and colour to the sauce.
The step that matters
Browning the seasoned steaks. Frying until browned drives the Maillard reaction, which builds the roasted, savoury flavour the stew depends on. Pale, steamed steaks will taste flat.
Swap the onion
