Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Release water as they cook down, concentrating their flavour into a thick, savoury base.
- Mushrooms
- Add earthy savour and a tender, meaty texture to the mixture.
- Bread crumbs
- Thicken the tomato and mushroom mixture so it holds together on the toast.
- Butter
- Adds richness and fat, carrying flavour and giving a smoother mouthfeel.
The step that matters
Cook the tomatoes until most water evaporates. Tomatoes are mostly water. If they are not reduced enough, the mixture stays thin and soaks the toast, leaving it soggy rather than spreadable.
