Melt the sugar in a pot and caramelise. Pour into four timbal moulds and leave to set. Bring milk to the boil. Remove the pot from the heat, add the pudding powder at once to the milk, stirring with a whisk, and stir in for about 1 minute. Add one half of the almonds.
Pour semolina pudding into the moulds and let it set in the fridge. In the meantime, wash the apple thoroughly, quarter and core it. Cut the apple quarters into pieces. Peel and slice the banana. Drain the mandarins and collect the juice. Mix apple, banana, tangerines, some juice and lemon juice. Roast remaining almonds in a pan without fat until golden brown. Pour over the fruit salad. Dip the pudding moulds briefly in hot water and turn them over.
