What each ingredient does
- Mushrooms
- Soften when covered over low heat, releasing moisture that gives the topping a tender, juicy texture.
- Butter
- Browns to add nutty, toasty flavour and richness to the mushrooms.
- Toast
- Provides a crisp base that holds the mushrooms and absorbs the buttery juices.
The step that matters
Browning the butter. Butter can go from golden to burnt quickly. Medium heat and watching for the first colour change give nutty flavour without bitterness.
