Bring ¾ cup of the water to a boil in a saucepan. Remove from heat and set aside.
In a heavy-bottomed saucepan, dissolve cornstarch in remaining 1¼ cups water. Place pan over medium heat and gradually add the boiled water, whisking constantly, until well combined. Add 2 cups of the powdered sugar all at once, whisking constantly until sugar is dissolved. Gradually add remaining 2 cups sugar, stirring constantly for 5 minutes or until mixture is thickened and bubbly. Add rose water and few drops of red food coloring. Stir until combined.
Mix powdered sugar and cornstarch and place half the mixture in a baking dish. Spread cooked sugar mixture in an even layer over the top. Let cool for awhile, then cover with another large amount of sugar-cornstarch mixture. Let cool completely.
Using an oiled knife, cut Malban into squares. Arrange on a plate, shaking off excess sugar and cornstarch.
