Peel and grate the carrots. Cook them till soft in 1 cup of milk. Cool and blend in a mixer.
Boil the remaining milk. Add cashew powder and sugar. Simmer for 2-3 minutes. Add Ragi malt and milk Masala. Add to carrot mixture (add gelatin if using).
Chill in the refrigerator overnight. Next day, beat the mixture till frothy. Place in a flat aluminium container in the freezer. When 1/2 frozen, beat till fluffy and return to freezer. Freeze till firm. During this time, stir with fork a couple of times. When frozen, transfer to a freezer container with lid and store in the freezer. If frozen too hard, soften in refrigerator before serving.
