Make up the jelly / jello with half the amount of water that is indicated on the packet. (ie For jell-o brand there is 10.3g of powder per sachet so make it up by dissolving the powder in ½ cup of boiling water and then add ½ cup of cold water. For Hartley's brand jelly there is 11.5g of powder per sachet so make it up by dissolving the powder in ¼ pint of boiling water and then add ¼ pint of cold water.

Stir then set aside to cool for a bit.

Spoon the drinking chocolate into a large bowl (or the bowl of a stand mixer if using). Add two tablespoons of the yogurt to the powder and mix so that it is lump free. Add the rest of the yogurt and stir to mix.

Using an electric whisk (or your stand mixer) whisk the yogurt for a couple of minutes until bubbles start to form.

Slowly pour the jelly / jello mixture into the yogurt in a steady stream continuing to whisk as you do so,.

Whisk for a further 4 or 5 minutes if you want a dessert that you can place in molds and turn out like the one in the photo. Alternatively, if you are wanting a more moussey consistency, then whisk for 5 - 10 minutes until lots of bubbles appear and the mixture has increased slightly in volume.

For Chocolate Orange Fluff that can be turned out, spoon the mixture into lightly oiled pudding molds and chill for a couple of hours. Release from the molds by running a sharp knife around the rim.

Alternatively, spoon the mixture into individual ramekins or glasses and place in the fridge to chill for at least 2 hours.
