Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bullock's liver
- Forms the main body of the dish, cooked tender by long gentle stewing.
- Potatoes
- Starchy bulk that holds its shape and soaks up the savoury flavour of the cooking liquid.
- Cabbage or carrots
- Adds moisture and mild sweetness, bulking out the dish with soft vegetable pieces.
- Lard or dripping
- Fat for frying that carries flavour and gives the pieces a golden, savoury surface.
- Flour
- Thickens the cooking liquid into a smooth sauce that coats the liver and vegetables.
The step that matters
Thickening the sauce with flour. Flour must be mixed in so starch can gelatinise in warm liquid; added dry or left unheated, it leaves lumps and a raw, floury taste.
Swap the cabbage
How well each one fits the dish's main ingredients (liver, potato, pepper, flour):
- Chivefits better
- Carrotfits better
- Spinachfits better
- Cabbagethe original
Fit is the average pairing score against liver, potato, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
