Chef's Pro-Tips

  • Mise en Place: Measure and prep all ingredients before you turn on the stove. This recipe moves quickly, and having everything ready prevents burning.
  • Fresh is Best: Whenever possible, use freshly squeezed lemon juice, whole garlic cloves, and fresh herbs instead of dried/jarred versions. The flavor difference is huge!
  • Don't Crowd the Pan: Leave room between ingredients. If the pan is overloaded, the moisture will steam the food instead of browning it.
