In a heavy pot, combine the unflavored gelatin, sugar, and salt.

Add water (incorporating rose water).

Bring the mixture to a slow boil and simmer gently for 10 minutes, without stirring.

Remove the pot from the heat and stir in the lemon juice (or orange juice) and grated lemon rind (or orange rind).

Add a few drops of food coloring to achieve the desired hue.

Taste the mixture and adjust the flavor by adding more juice if needed.

Pour the mixture into an 8-inch square pan that has been rinsed with cold water but not dried.

Chill the pan in the refrigerator overnight to allow the Turkish delight to set completely.

Once chilled and firm, cut the Turkish delight into small squares.

Roll each square in powdered sugar to coat it evenly.
