Semolina cakes are traditional in Lebanon and throughout the Middle East. This one is soaked in simple syrup scented with flower waters, and is my version of a wonderful cake made by my friend Suzy at The Mediteranean Dish. For the decoration, I was inspired by the beautiful rose cake at Saveur. Be sure to use unsprayed roses, or any unsprayed edible flower. Alternatively, decorate the cake with just the toasted coconut. Serve small pieces with strong coffee--this is a very sweet cake!
Make the sugared rose petals ahead so they can dry for at least one hour. Whisk the egg white in a small bowl until it is frothy. Place the superfine sugar in a small bowl. Use a pastry brush to lightly but thoroughly coat a rose petal with the frothed egg white. Be sure to cover the edges completely. Dredge the petal in the sugar, gently shaking off extra sugar. Place the petal on a parchment lined sheet pan. Repeat this with all of the rose petals and set them aside to dry.
Preheat the oven to 350 degrees. Butter a 9-inch springform pan, and line the bottom with parchment. In a large mixing bowl, mix the sugar, salt and yogurt with a large spoon. Stir in the semolina, ½ cup of the coconut, baking powder, milk, and melted butter, continuing to stir until combined.
Scrape the batter into the prepared pan, and bake for about 45 minutes, or until golden. Then place the pan under the broiler for just a few seconds, until the top is deep golden brown (take care; it can burn easily).
Make the simple syrup while the cake is baking. In a medium saucepan, combine the water and sugar over medium high heat. Bring to a boil, then reduce the heat to simmer for 5 minutes. Remove the pan from the heat and stir in the lemon juice and flower waters. Cool the syrup to room temperature; this can be done swiftly by placing the pan in an ice water bath.
When the cake comes out of the oven, slowly pour the cool syrup over the hot cake, allowing the syrup to absorb completely. Cool for at least one hour before unmolding the cake from the pan.
Transfer the cake to a serving platter. Arrange the sugared rose petals on the cake to form a flower shape, starting with an outer circle of petals, then and interior circle of petals overlapping the outer circle, and a couple of petals in the middle.
Dust the petals and the perimeter of the cake with the remaining toasted coconut. Serve slices of cake at room temperature.
