This simple condiment uses highly flavorful ingredients, and a little chilling time, for big flavors. Use an unripe mango here for the best texture.
Stir together jalapeño, lime zest and juice, and ginger in a medium bowl until combined. Add mango, cucumber, bell pepper, curry leaves, cilantro, salt, and sugar, and stir to combine. Cover and refrigerate at least 1 hour or up to 8 hours before serving.
