Ouu Khatta (Odia: ଓଉ ଖଟା) is a sweet and sour chutney or marmalade made of ouu (elephant apple; Dillenia indica) in jaggery, in the Indian state of Odisha, mostly in post-monsoon season. Sometimes ouu is added to dal or dalma. It is rich in vitamin C.
According to popular Odia legends ouu plant was only found in Paradise. Goddess Parvati brought it to earth along with the betel vine.
As it is a sour fruit, it is cooked with jaggery or sugar. People who don't like sugar also prepare it with tangy mustard and garlic paste based gravy, along with red chilli powder.
