Let the coffee cool completely, then stir in the Amaretto syrup to taste.
Whip the heavy cream with the caster sugar until stiff peaks form, then fold in the mascarpone.
Take half of the ladyfingers and briefly dip them in the cold coffee with syrup, then place them in the serving dish (don’t dip them too long, or they’ll get soggy and break).
Cover the bottom of the baking dish with half of the ladyfingers.
Slice half of the strawberries into thin slices and arrange them over the ladyfingers.
Spread half of the mascarpone/whipped cream mixture over this.
Repeat this process and finish with a layer of mascarpone/whipped cream on top.
Now place the strawberry tiramisu in the refrigerator for at least 4 hours, but ideally overnight to set.
Before serving, garnish with some extra fresh strawberries and serve. Enjoy!
