# Expert Suggestions:

01 -
  • It comes together in less time than it takes to sear a steak, yet tastes like you've been fussing over it for hours.
  • One batch transforms whatever you're cooking—beef, fish, vegetables, or even warm bread—into something people will actually remember.
  • The balance of tang, heat, and richness feels intentional, never overdone or one-note.
02 -
  • Don't let the garlic brown even for a second—the moment it picks up color, that bite turns into something acrid and the whole sauce suffers for it.
  • Adding the fresh herbs after you take it off heat is the difference between this tasting alive and tasting like an old vegetable bin; temperature matters more than you'd think.
03 -
  • Zest your lemon before you juice it—trying to zest a squeezed lemon is a lesson in frustration that teaches you nothing except to plan better next time.
  • Keep your heat low throughout; this isn't a sauce that needs aggressive cooking, it needs attention and gentleness to become what it's supposed to be.
