To make the Brownies: Put the chocolate and butter in a large bowl and set it over a saucepan of simmering water or place in the microwave. Stirring occasionally, until the chocolate and butter are completely melted and smooth.

Remove from the heat and set aside to cool a little.

Add the sugars. Whisk until completely combined. The mixture should be room temperature.

Whisk the eggs and vanilla in a jug together.

Add a little of the eggs to the chocolate mixture and whisk until combined. Add the remaining eggs and whisk until combined. Do not overbeat the batter at this stage or your brownies will be cakey.

Sift the flour, salt and cocoa over the chocolate mixture. Using a rubber spatula (not a whisk), fold the flour mixture into the chocolate until just a bit of the flour mixture is visible. Set aside.

To prepare your oranges: Carefully takes a seated knife and take out the center of the orange.

Once you take a bit out you can go in with a spoon and scoop the rest out. You don't have to take out all of the pulp.

Pour the batter into your orange 3/4 of the way. Place it's lid on and wrap in tin foil

Place directly on the grills on medium heat (350oF/180oC) and bake for roughly 35-45 minutes.

Enjoy straight away with Vanilla ice cream.
