In a large, wide pan (1 use 12 inch kadai), combine 1 cup of sugar with 5 cups water. Stir until the sugar dissolves completely.
Place over high flame and bring the syrup to a full boil (rolling boil) over high heat.
Without reducing flame, carefully slide the chenna patties into the boiling syrup, one by one.
Cover the kadai with a lid and let the rasmalai discs cook in the boiling syrup for 10-12 minutes. Keep the heat on high during this time. Don't peek. Meanwhile, in a large bowl, prepare a ice bath (water + ice cubes).
After 10-12 minutes, the patties should have doubled in size and should be light and spongy. Switch off the stove.
Immediately, remove the chenna balls using a from syrup using a slotted spoon and place in ice water bath for at least 30 minutes. This allows them to stop cooking and cool down.
Gently squeeze out the water from each patty by pressing it between your palms. This makes sure that they will absorb the ras. Be careful not to break them.
Place the patties into the room temperature ras. Make sure that they are fully submerged in milk mixture. Allow them to soak refrigerated for at least 5-6 hours or overnight is the best.
Serve rasmalai chilled garnished with extra nuts if desired. Store in an airtight container refrigerated and try to finish it in 3-4 days.
