I had friends over the other night and I decided to make Tiramisu. The origins of Tiramisu are widely debated, but it appears to have been invented in Treviso in the 1980s. One of the most popular Italian cakes, it is made of Savoiardi (also known as ladyfingers biscuits) dipped in espresso (with Marsala wine) and a whipped mixture of eggs, mascarpone and sugar. My recipe is a non-alcoholic version of the traditional one. I like it better this way because I find it is lighter. If you prefer the heavier version you just need to add some Marsala wine to the espresso used to soak the Savoiardi biscuits.
