Celebrity Chef Marcus Samuelsson says using meal-kits is a smart way to "enter" cooking. The restaurateur says he's learned that people get their start in the kitchen through so many different ways and that the key is to just give it a try, no matter what your background knowledge. The Red Rooster chef also offers advice on how to substitute oils such as avocado, saffron, and coconut in recipes that traditionally use olive oil. Samuelsson says these swaps can elevate the flavor of the dish...and give it some extra nutritional value to boot! Last spring, Samuelsson took his hit Harlem restaurant across the pond. Red Rooster opened in the city's Shoreditch neighborhood and is just one of the places where the renowned chef is expanding his culinary footprint.
