04. Leaves

Leaves produce energy for a plant by transforming sun and air into sugar (photosynthesis). To do their job, leaves are broad and flat so that they can capture the maximum amount of sunlight and water. Inside, they have a network of air pockets to help the flow of carbon dioxide and oxygen through the cell walls where photosynthesis takes place. This aerated framework makes leaves much more susceptible to dehydration and bruising than other vegetables. Although they are the most delicate part of a plant, some leaves are heartier than others, and these hearty ones are the best choice for grilling. Cabbage, Brussels sprouts, Belgian endive, radicchio, and romaine all grill beautifully.
