A tourist:  "Excuse me, can you tell me the name of this food?"

Food seller: "We call this food lemper, Sir", our traditional food.

A tourist: "Lemper? Can you tell me what it is?"

Food seller: "Sure. Lemper is made of a handful lump of steamed glutinuous rice. It is filled with chicken or beef filling. Each piece is wrapped in a banana leaf, and the wrapping is secured on both ends with tooth picks or "lidi".

A tourist: "Then, what will you do after you wrap them in banana leaves?"

Food seller: "Steam or cook them for about 30 to 60 minutes. It also can be served straight away with the banana leaves still green and fresh.

A tourist: "Oh I see. Thank you for your nice explanation. I think it is really a delicious food. I will try some."
