Wash the orange to get rid of any surface grime, and remove any leaves and the nubbly bit at the end (you know the bit I mean ...). Chop it all up, skin and all, into rough chunks so that your blender doesn't explode when you whizz everything together.
Add a couple of tablespoons of yogurt - just enough to make the eventual pudding smooth and creamy. The orange and cardamom should be the stars, rather than the yogurt.
Crack a couple of cardamom pods and drop the fragrant black seeds in with the orange and the yogurt.
Add a tablespoon of honey and blitz the whole lot with a stick blender until smooth and light. It can be eaten as is at this stage, or put into the freezer to make a fabulous frozen pudding. Delicious.
