Watermelon-rind chutney is actually an old-fashioned sweet pickle. It's made modern with ginger and Thai chiles, which enliven the crisp rind's naturally cool qualities. It pairs beautifully with succulent Asian-style spareribs.
Ginger and chiles give this Southeast Asian rendition its aroma and spice, while lemongrass lends the soup a seductive floral note. By swapping the traditional seasonings for more exotic ones, you achieve a soup that's just as soothing as the original but with nuanced layers of flavors.
