Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Long cooking breaks down the tough connective tissue, leaving the meat tender and flavourful.
- Onions
- Break down during the long cook, adding sweetness and depth to the gravy.
- White turnips
- Hold their shape during the long cook and add a mild, slightly peppery flavour to the stew.
- Potatoes
- Soften as they cook and help thicken the liquid with their starch.
- Flour
- Starch that thickens the cooking liquid into a smooth gravy when blended in cold water first.
The step that matters
Thicken the gravy with flour blended in cold water. Flour added directly to hot liquid clumps, because its starch grains swell unevenly. Blending it smooth in cold water first lets the starch disperse so the gravy thickens evenly.
Swap the turnip
How well each one fits the dish's main ingredients (beef, onion, flour, potato):
