Step by step
Remove the strawberries from their juice and pour the juice into a bowl with the sponge fingers (or if you blended the strawberries, add the puree instead).
Tips
Make this dessert when strawberries are in season; out-of-season strawberries cost much more and will either be a from a greenhouse or come from abroad.
Trivia
To get an even fresher and more delicate result, strawberry tiramisù can also be made with ‘robiola’ cheese instead of mascarpone and substituting plain yoghurt for the cream.
