Turn off the heat. Add the rose water, orange blossom water and mastic gum.

To prepare the ashta cream: Cut off the edges of the bread. Discard. Cut in dices the soft white part. Place the bread dices in a saucepan and pour the milk and whipping cream over them. Let the bread dices soak in the milk and cream mixture for at least 2 hr in the refrigerator. Put the saucepan on medium heat and, with a wooden spoon, start stirring the bread and milk mixture. Once the milk starts heating, add the water-dissolved cornstarch. Continue stirring until the mixture thickens. Once done, pour in a bowl and leave it to cool.
