sufficient water in a deep non-stick pan for 15-20 minutes. Place a muslin cloth in a strainer and strain the nannari mixture into a bowl.

nannari water into another deep non-stick pan, add sugar, mix and cook on medium heat till the mixture reduces and becomes syrupy. Set aside to cool down to room temperature.

syrup into each of 4 tall glasses. Add 2 lemon slices, 5-6 mint leaves and ½ tsp lemon juice in each glass and mix.
Add ½ tbsp rose
syrup, 2-3 ice cubes to each glass and top with chilled water. Mix well and serve chilled.
