For panch phora, dry-roast all spices in a small frying pan until fragrant (1-2 minutes), then set aside.
Heat half the oil in a large frying pan over medium-high heat, add half the okra and half the panch phora and fry, tossing occasionally, until okra is golden (4-6 minutes; be careful not
to burn the spices). Season generously, transfer to a plate and keep warm. Repeat with remaining oil, okra and panch phora. Serve warm with lemon wedges.
