Vietnamese pepper Lalot - Piper sarmentosum

Piper sarmentosum is native to the tropical areas of Southeast Asia, Northeast India and South China, and as far as the Andaman Islands. Piper lalot is now known to be the same species (synonym). Under this name - Lalot - it is cultivated for its leaves which is used in Lao and Vietnamese cuisine as a flavoring wrap for grilling meats. There is no "official" English name for it, but it is sometimes called Wild Betel. The leaves are often confused with Piper betle but they lack the intense taste of the betel leaves and are significantly smaller.

Delicios healthy food with Lalot

The practice of wrapping meat in vine leaves originated in the Middle East, which was taken to India by the Persians. It was subsequently introduced by the Indians to Southeast Asia. However, grape vines do not grow well in tropical climates, so the Vietnamese started to use leaves of lalot instead. Subsequently, the use of lalot in cooking spread to the entire Indochina region, and recently introduced to the United States by Lao and Vietnamese immigrants.

In Vietnamese cuisine it is used in Bo La Lot (Bo Nuong La Lot), a typical Southern Vietnamese dish. Minced beef is marinated with seasoning, soya sauce and various finely chopped spices such as garlic, onion and lemongrass then wrapped in Piper lolot leaves and grilled, which brings smokey flavor to the beef. It is served with rice noodles, fresh herbs, sliced star fruits and pineapples, and fermented fish sauce.
