Toast the saffron strands very lightly. Crush the saffron strands finely and place in a small bowl. Add milk and crushed seeds. Stir well and leave to cool.
Melt the butter in a frying pan, add sugar, cassia or cinnamon and stir well. Peel and slice the bananas and fry both sides gently for about 1 minute. Remove from the pan and place the fried banana slices in the serving glasses.
Mix the yogurt with the cold spiced milk and the honey. Spoon the mixture on top of the banana and liberally sprinkle the surface with toasted flaked almond. If wished, chill before serving.
