Pour the boiling water along with the pineapple into the kadai with the ghee roasted rava. Pour slowly and gently as the rava will spit and splutter initially. Keep heat low and stir continuously. In about a minute, the rava would have absorbed all the water and increased in volume. At this stage, tip in the sugar and keep stirring. The kesari will again loosen up and become fluid. Don’t worry. Your sugar is melting. Keep stirring. The kesari will again start thickening. This may take 2-3 minutes. When the kesari leaves the sides of the pan, it is done. Switch off. Add back the fried cashews and raisins and mix them in. Serve hot or at room temperature. Enjoy!
