Origin
Nam manao, literally lime water, belongs to the everyday tradition of Thai sweet drinks and is made throughout the central plains and in Bangkok, where it is sold from street carts, market stalls and small shops as well as made at home. It is a drink of the household and the roadside rather than of any court or ceremony, and it is carried by ordinary cooks and vendors who squeeze the fruit to order. Leela Punyaratabandhu, in Bangkok, places such drinks within the daily repertoire of the city's vendors and home kitchens.
Description
Nam manao is a cold drink of freshly squeezed lime juice, sugar syrup and water, served over ice, with a pinch of salt in many versions. The fruit is the small, thin-skinned, highly aromatic Thai lime, manao, Citrus aurantiifolia, whose juice is sharply acidic and fragrant; it is not the larger Persian lime, and it is not the makrut lime, Citrus hystrix, which is grown for its leaf and rind. The drink is judged on the balance of sourness and sweetness, on clean fragrance, and on a clear, bright appearance.
The Thread
Flavour Context
Nam manao is drunk beside rich, fried, grilled and chilli-hot food, and it is taken alone in the heat of the day. Its acidity cuts through fat and refreshes a palate burned by chilli, while its sweetness softens the sting, and the ice and salt make it quenching. This is the same structural logic of sour, sweet and salt that governs the savoury Thai table.
