Bring a small saucepanful of water to the boil, and add a splash of white wine vinegar. Boil the egg for five and a half minutes.
In the meantime, toast the sourdough and then spread with In A Pickle Sweet Chilli Jam. Peel the avocado and remove the stone, and then mash half onto each of the slices using the back of a fork.
When the timer goes for the egg, transfer it to a bowl of cold water for a minute or so, and then peel off the shell (the white wine vinegar in the water should make this easier). Cut the egg in half and lay on top of the toast, and then sprinkle with coarse sea salt, freshly ground black pepper, fresh coriander and a squeeze of lime.
