# Expert Advice:

01 -
  • It takes 15 minutes total but tastes like you spent an hour perfecting it.
  • One batch transforms steak, fish, vegetables, or even bread into something people will ask about at the table.
  • The balance of heat, tang, and richness feels fancy without any pretense.
02 -
  • Don't let the butter brown—it turns bitter and ruins the whole sauce, so medium-low heat is your friend.
  • The herbs go in last and off the heat because boiling them kills their brightness; you want them to just warm through.
03 -
  • Buy a microplane zester for the lemon—it gives you fluffy, flavorful zest that a regular grater just can't match.
  • Room-temperature ingredients mix more evenly, so pull your butter out 10 minutes before you start if your kitchen is cold.
