Decide how you’ll use the cheese: grating/finishing, melting in hot dishes, or serving on a board.
Match flavor intensity: choose Comté or Gruyère for mimolette’s nutty depth; choose Parmesan/Asiago for salty, aged bite.
Apply the listed ratio (e.g., Parmesan ¾ for 1):1 swaps) and grate more finely for smoother melting.
If the substitute is softer (like Taleggio), chill briefly so it firms up for slicing or topping.
Taste after mixing: add a pinch of salt if you used a milder cheese (Emmental), or balance sharpness with a bit of fat (butter/oil).
