Halve the passion fruit and scoop the pulp into a large bowl. Add the yogurt and mix them together gently.
Put 2 tablespoonfuls of the honey in the bases of two narrow glasses and scatter with half of the hazelnuts. Spoon half of the yogurt over the nuts and arrange half of the clementine pieces on top of the yogurt.
Repeat the layering, reserving a few of the nuts for decoration. Scatter the nuts over the top and chill the yogurts until you are ready to serve them.
