Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef skirts
- Main protein that browns under the broiler for savoury flavour.
- Brown gravy
- Liquid base that carries the flavour and keeps the beef moist.
- Mushroom ketchup
- Adds concentrated savoury depth to the gravy.
- Shallot vinegar
- Adds acidity that sharpens and balances the rich gravy.
- Butter
- Adds fat and richness, giving the thickened gravy a smooth mouthfeel.
- Flour
- Thickens the gravy as its starch swells in the hot liquid.
The step that matters
Thicken the gravy with butter and flour. Cooking the flour in the butter before adding it to the liquid coats the starch grains, so the gravy thickens smoothly without lumps or a raw, pasty taste.
Swap the shallot
