Five ingredients and five minutes is all that's needed to make this Instant Shahi Tukra.
Do not use Cake Rusk, we want the dry kind that we dunk in tea. The thickness of the rabri depends on the wattage of the microwave and milk used. Adjust the timing of the microwave and the amount of milk accordingly. Keep in mind that the rabri thickens as it cools. I used 12 Rusk and saved some rabri for pouring on top, just before serving. The rabri thickened in the fridge, I added a few tbsp of milk and microwaved for 1 minute before serving and garnishing.
