Raita

The history of raita as a side dish can be traced at least to the 12th century, when a form of it appears in the Manasollasa (1137 CE), suggesting that its roots lie in the medieval period; later evidence from the Ni‘matnāma around 1500 CE shows it more clearly as part of established courtly cuisine.
