Nước rau máPennywort juice
Saigon street carts blend nước rau má to order through the hottest part of the afternoon, pouring the bright green juice into plastic cups over crushed ice for office workers and students. Pennywort (rau má) tastes fresh, grassy and very slightly bitter, and southerners drink it to 'cool the body' in the dry season; some stalls blend in cooked mung beans or a splash of coconut milk to make it richer. Look for bunches of rau má in Vietnamese and South Asian grocers, where it is also sold as gotu kola. Chef's tip: strain twice through a fine cloth and drink it within the hour; left standing, it separates and darkens to a dull khaki.
