Cut the edges of the bread if you prefer it without edges, then place it in a baking dish and toast in the oven until golden at 350°F.
While waiting for the bread, make the simple syrup by mixing sugar and water, bring to a boil, then add lemon juice and orange blossom water.
Let it boil for another 2 to 3 minutes, then remove from heat.
Take the toasted bread out of the oven, ensuring both sides are golden. Pour all the simple syrup on top, making sure all the bread is soaked.
Begin making the ashta by mixing whipping cream, full-fat milk, sugar, cornstarch, and orange blossom water.
Mix everything together until combined, then turn on the heat.
Keep stirring until it thickens.
Pour the ashta evenly on top of the bread.
Sprinkle with crushed pistachios or any kind of nuts you like.
Decorate with rose petals.
Let it cool down completely.
Cover and refrigerate for at least 6 to 8 hours before serving or overnight.
Using full-fat milk is recommended if you want that rich flavor in your dessert. You can use whipping cream instead of full-fat milk. So, instead of 2 cups whipping cream and 2 cups full-fat milk, use 4 cups whipping cream (IL).The bread can be toasted in the toaster, air fryer or oven.
