- Place the apple, vanilla and honey in a pan and cook gently until just softened. Add the blackberries (keep back a few for decoration) and cook gently until all the fruit is soft.
- Put a couple of the blackberries in the base of each serving dish. Leave the rest until cold. Then gently mash or lightly beat the fruit together without turning it to puree.
- Whisk the egg white until standing in peaks and fold this into the fruit puree along with the yoghurt but don't fold too much.
- Divide evenly between the four serving dishes and leave to chill. Serve the blackberry and apple fool decorated with the remaining fruit and mint leaves.
