# Expert Advice:

01 -
  • The way the Gruyère forms this incredible golden crust while staying creamy underneath is pure magic
  • It transforms humble ingredients into something that feels like a special occasion
02 -
  • Slice your potatoes as thin and uniform as possible or you will have some pieces undercooked while others turn to mush
  • Do not let the cream mixture boil or it might separate and create an unappealing texture
03 -
  • Grate your own cheese instead of buying pre shredded which contains anti caking agents that prevent proper melting
  • Place your baking dish on a rimmed baking sheet to catch any potential bubble overs
