At the Lello table
A crisp, buttered sandwich of Comté, caramelized onions and a thin layer of truffle mustard. The recipe is written to keep the featured pantry ingredient precise and recognizable rather than overwhelming the plate.
Method
- Cook the onion in butter over medium-low heat until caramelized.
- Spread truffle mustard thinly inside each sandwich. Add cheese and onions.
- Butter the outsides and cook slowly in a covered skillet until crisp and fully melted.
Cook’s notes
- Taste before adding more salt; the featured pantry ingredient should remain clear and balanced.
