Cooking Technique Details from Authentic Vendors

• Heat management: Work over lively heat for colour, and speed without drying.
• Batching: Cook bases in small rounds; hold finished components briefly, and assemble to order.
• Seasoning: Salt early for penetration, adjust at the counter with salsas, and pickles.

Common Variations Across Different Regions

• City vs village: Urban stalls lean richer, and saucier; rural versions run simpler, and herb‑forward.
• Heat levels: Choice of chilli varies; offer mild to hot salsas on the side.
• Service style: Hand‑held for queues, plated with salads at sit‑down counters.

Pairings with Drinks, Sides, and Sauces

Think crisp salads, quick pickles, and a duo of sauces (one bright, and mild, one smoky, and hot). Cold beer, tangy soft drinks or aguas frescas keep the palate refreshed. Bread or flatbreads nearby to mop up juices never go amiss.
