Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mushrooms: Provide the main body and earthy flavour of the sauce as they soften in the gravy.
Rich brown gravy: Forms the liquid base that carries the mushroom flavour and gives the sauce its body.
Mushroom ketchup: Adds concentrated mushroom flavour and savoury depth to finish the sauce.
Thickening: Thickens the liquid so the sauce coats the back of a spoon.
