Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh mushrooms
- Form the main topping and, cooked gently in butter, release savory flavor and tender texture.
- Tomatoes
- Provide acidity and fresh flavor, and their pulp adds moisture to the topping.
- Butter
- Carries the mushrooms' heat and adds richness and browning-related flavor.
The step that matters
Cook the mushrooms gently. Mushrooms hold a lot of water. Cooking them slowly lets that moisture evaporate so they brown and taste concentrated rather than steaming soggy on the toast.
Swap the tomato
How well each one fits the dish's main ingredients (mushroom, butter, pepper, parsley):
- Shallotfits better
- Carrotfits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against mushroom, butter, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
