Open the can of pineapple slices and separate the slices from the juice. Keep the juice to add to the yogurt to enhance the flavour of the raita and adjust the consistency (step 4).
Chop the pineapple slices into small to medium-sized pieces according to your preference. Reserve a tablespoon of the chopped pineapple for garnish.
Next, in a bowl or in a serving dish, whisk the yogurt until smooth.
Add a pinch of salt to the whisked yogurt and gradually combine 1-2 tablespoons of the pineapple juice at a time to the whisked yogurt to get a thick but flowing consistency. The quantity of juice needed will depend on the desired consistency of the raita, so adjust as per preference.
Taste the yogurt mixture and, if needed, gradually add and mix in 1-2 teaspoons of powdered sugar at a time to sweeten it. The quantity of sugar needed will depend on the tartness of the yogurt.
Once the yogurt reaches your desired level of sweetness, add the chopped pineapple pieces.
Reserve some mint leaves for the garnish & gently tear the remaining mint leaves into small sized pieces using your hands and add to the yogurt bowl.
Gently combine the pineapple pieces & the mint with the whisked yogurt.
Garnish the raita with the reserved chopped pineapple pieces and mint leaves.
Serve the raita as a side dish or dessert.
