Chef's Tip for Extra Flavor

Elevate your dish with simple flavor boosters! A final flourish of freshly chopped herbs can add incredible brightness, while a squeeze of lemon or lime juice right before serving can awaken all the flavors. Don't underestimate a sprinkle of quality finishing salt or a drizzle of good olive oil to make your creation shine.
