Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Starch thickens the strained liquid into a body-rich gravy as it heats.
- Butter
- Fat carries flavour and combines with flour to help thicken the gravy smoothly.
- Mushroom ketchup
- Adds savoury depth and dark colour to the gravy.
- Onion
- Stewing softens its sharpness and adds aromatic sweetness to the stock.
- Carrot
- Contributes gentle sweetness and body to the stewed liquid.
The step that matters
Thickening the strained liquid with butter and flour. Raw flour added straight to liquid clumps and tastes pasty. Mixing it smoothly with butter and letting the liquid heat lets starch granules swell evenly, giving a smooth, lightly thickened gravy.
Swap the mace
