Creating Rosewater and Pistachio Delight can be a straightforward process if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a baking dish (8×8 inch) with butter or cooking spray.
2. Mix Dry Ingredients: In a large bowl, combine the semolina, sugar, baking powder, and salt. Stir well to mix thoroughly.
3. Combine Wet Ingredients: In another bowl, mix the melted butter, milk, and rosewater until well combined.
4. Combine Mixtures: Gradually add the wet mixture to the dry ingredients, stirring until you have a smooth batter.
5. Add Pistachios: Gently fold in the chopped pistachios, ensuring they are evenly distributed throughout the batter.
6. Pour into Baking Dish: Pour the batter into the prepared baking dish, smoothing the top with a spatula.
7. Bake: Place in the preheated oven and bake for 30-40 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
8. Cool: Once baked, remove from the oven and allow it to cool in the dish for about 20-30 minutes.
9. Cut into Pieces: After cooling, cut the delight into squares or diamonds, depending on your preference.
10. Dust with Powdered Sugar: Before serving, dust the top with powdered sugar for a beautiful finish.
