Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Cook down and brown on the grill, giving the toast its main savoury flavour and soft texture.
- Butter
- Adds richness and moisture, and helps the mushrooms and bread brown when grilled.
- Wholemeal bread
- Forms the base that soaks up butter and juices and holds the mushrooms.
The step that matters
Grilling the mushrooms over a clear fire. Mushrooms are mostly water. Over a clear, steady heat the surface can brown before they release too much liquid, which concentrates flavour. A smoky or flaming fire can scorch the outside while the centre stays raw.
Swap the parsley
How well each one fits the dish's main ingredients (mushroom, butter, pepper, bread):
- Thymefits about as well
- Parsleythe original
- Marjoramfits about as well
- Sagefits less well
Fit is the average pairing score against mushroom, butter, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
