Melt the chocolate and butter in the top of a double boiler until smooth, stirring constantly. Remove from heat, and stir in the granulated and brown sugars, espresso powder, salt, vanilla, orange juice, and orange zest. Whisk in the eggs until the batter is smooth, then stir in the cocoa powder. Add the almonds and stir until they're evenly distributed throughout the batter.
Pour the batter into the cake pan and place the pan in the oven. Bake for 25-30 minutes, then remove it from the oven and allow to cool for 10 minutes before running a thin rubber spatula along the edge of the cake to loosen it, then remove it from the pan and allow to cool for another 20 minutes before garnishing with the cocoa powder, sea salt, and violets. Serve immediately alongside the syruped oranges.
Cut the peels off the oranges and then cut them into eight slices per orange. Set aside.
Bring the suhar and water to a rapid simmer over medium heat. Reduce to low and add the orange slices and allow to simmer for 20 minutes, then remove from heat and allow to cool to room temperature.
