For the pudding, measure 1/2 litre of milk. Mix pudding powder and 50 g sugar with 4 tablespoons of milk. Bring the remaining milk and espresso powder to the boil. Remove the milk from the stove and stir in the pudding powder.
Add chopped almonds and fold in. Bring to the boil again while stirring. Put the pudding into 4 round moulds (approx. 150 ml content) rinsed with cold water. Smooth it down and put it in a cool place, preferably overnight.
For the vanilla foam, mix sauce powder and the remaining sugar. Take 3 tablespoons of the remaining milk and mix with the sauce powder. Bring the rest of the milk to the boil. Remove from heat and stir in the sauce powder.
Bring to the boil again while stirring. Leave to cool. Use a knife to remove the pudding from the rim of the mould and turn it out onto plates. Beat the vanilla sauce with a hand blender until frothy. Roast the flaked almonds in a dry pan until golden brown.
Pour the sauce onto the plates and sprinkle the pudding with flaked almonds. Dust with icing sugar and serve decorated with mint flakes as desired.
