You will also need 4 x pretty glasses, sundae glasses or short tumblers.
Whisk the mascarpone and yogurt together until smooth.
Reserve 4 strawberries, 8 raspberries and 8 blueberries for decoration, then lightly mix the other fruits together in a small bowl and dust with 2 teaspoons icing/powdered sugar to sweeten.
Crush the biscuits.
Now begin layering the glasses. First, divide half the biscuits between the glasses, spreading them evenly over the base. Sprinkle 2 tablespoons of the Marsala (or whatever you are using) over the biscuit crumbs.
Spoon a quarter of the mascarpone mixture over the biscuit crumbs and smooth the surface.
Next, divide half the fruit between each of the glasses and then layer with another quarter of the mascarpone mixture and smooth the surface.
Now, sprinkle the remaining biscuit pieces over the mascarpone mixture and add 2 more tablespoons of the Marsala (or whatever you are using). Add another quarter of the mascarpone mixture and smooth the tops.
Finally spoon over the remaining fruit and finally the last quarter of the mascarpone mixture.
You should now have 4 layers of the mascarpone mixture, 2 layers of the amaretti biscuits and 2 layers of fruit.
Halve the reserved strawberries and decorate each glass with the reserved fruit.
Sieve over a dusting of icing/powdered sugar just before serving.
170g (6 oz) strawberries, hulled and halved (⅞ cup)
170g (6 oz) blueberries (1 cup)
For the custard
150ml (5 fl oz) whole/full fat milk (⅔ cup)
150ml (5 fl oz) single cream/table cream (⅔ cup)
2 eggs, large (U.K.)/extra large (N.A.)
28g (1 oz) caster/white sugar (2 tbsp)
½ tsp vanilla extract
Single cream/table cream
a shallow ovenproof dish with a capacity of 600ml (20 fl oz) (3 cups)
a small roasting tin/pan
For the fruit compote
Wash the plums, halve and remove the stones. Pour 300ml (10 fl oz) of water into a pan, add the sugar and stir over a medium heat until the sugar has dissolved. Bring the syrup-water to a simmer and add the plums. Cook for one minute. Remove from the heat, cover and leave for 10–15 minutes until the fruit has softened but still keeps its shape.
Meanwhile, wash the berries, hull and halve the strawberries. Add them to the plums and stir to distribute the fruit. Transfer the fruit to a serving dish, cover and chill for 24 hours.
For the custard
The next day prepare the custard.
Heat the oven to 170°C (325°F) (gas 3)
Pour the milk and cream into a mixing bowl and add the eggs, sugar, and vanilla extract. Whisk to combine and then strain the custard into the ovenproof dish.
Pour the custard into the ovenproof dish and place this in the roasting tin/pan. Then slowly pour cold water into the roasting tin/pan to a depth of at least 2.5cm (1 inch). Carefully slide onto the middle rack in the oven and bake the custard for 50 minutes until it is set but still has a slight wobble in the centre when gently moved. It will also have an attractive golden skin. Remove from the oven and allow to cool for 20–30 minutes.
Remove the fruit compote from the fridge to bring it to room temperature.
Divide the custard between four dessert dishes and then spoon the compote around. Cream can also be poured over for a little bit of extra indulgence.
Finely grate enough of the lemon peel to produce ½ teaspoon and set aside. Then juice the lemon.
Make up the jelly/jello according to the packet and add 2 tablespoons of the lemon juice. Refrigerate until partially set (the consistency of unbeaten egg whites).
Stir the berries into the jelly/jello and then pour the berry mixture into the dish and refrigerate until the jelly has completely set.
Meanwhile, remove the cream cheese from the fridge and let it come to room temperature (about 1 hour).
Once the jelly/jello has set, whip the cream until it forms soft peaks.
Cube the cream cheese and add to the cream, then sift in the icing sugar and beat well until combined. The mixture will become fluffy and thicken. Stir in the grated lemon peel.
Carefully spoon the cream cheese mixture evenly over the jelly mixture and gently level with a palette knife making sure the mixture reaches the edges. Refrigerate for a further 1 hour.
Heat a small frying pan/skillet and tip in the nuts. Over a gentle heat stir the nuts to toast them. This will only take a few minutes. They are ready when they have turned a light golden colour and they begin to smell nutty. Remove from the pan and set to one side to cool.
To serve, sprinkle the nuts over the cream cheese mixture and cut into 6 portions. The first portion is always tricky to remove from the pan but then it becomes much easier.
