Savoiardi For White Tiramisu

Our answer

Nigella's White Tiramisu (from HOW TO EAT) differs slightly from a classic tirmaisu as it soaks savoiardi biscuits (cookies) in a mixture of milk and white rum, rather than a coffee-based liquid.

Savoiardi biscuits are light, dry, sponge-like biscuits. The name "savoiardi" is the Italian name and you may find them under this name in US grocery stores. They are also called ladyfinger cookies in the US. In the UK and Australia they are also called sponge fingers or boudoir biscuits. If you can't find the biscuits then you could use a vanilla pound cake, or madeira cake, cut into 1cm/1/2-inch slices. Leave the slices on a wire rack to dry out overnight and then cut into fingers or sticks. The cake will not be as dry as the savoiardi, so you may need to brush the milk and rum mixture over the cake rather than soaking it in the mixture.
