Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt beef
- Provides the main savoury, meaty flavour and the chunky body of the hash.
- Onions
- Frying until browned turns their sugars into sweetness and deep, savoury flavour.
- Potatoes
- Their starch softens and partly thickens the hash, binding it together.
- Carrots
- Add natural sweetness, colour and a tender bite to the mixture.
- Butter
- Carries the frying of the onions and adds richness and browned, nutty flavour.
- Stock
- Supplies the moisture that keeps the hash from drying out while it simmers.
The step that matters
Frying the onions until nicely browned. Browning caramelises the onions' natural sugars, giving sweet, deep flavour. Pale, underdone onions taste raw and flat, and that flavour carries through the whole hash.
