Sugared or Salted Fruit (Ô mai)

O mai is a traditional snack and a specialty of Hanoi. The term refers to preserved sugared or salted fruits such as apricot, dracontomelon (sau), peach, plum, tamarind, pineapple, mango, star fruit, and kumquat. The fruits are first checked to ensure that they are of the same size and without bruises.

They're then thoroughly cleaned and pricked so that they can absorb sugar more easily. The sugar is mixed with salt, water, often ginger and chili, and a bit of lime juice, which keeps the fruit's natural color in check. The fruits are cooked, fermented, and finally dried before they're sold, usually all along the Hang Duong Street in Hanoi.

O mai is especially popular as a snack during Tet (Vietnamese New Year). It's recommended to serve these fruits with a cup of lotus tea on the side.
