I used the crunchy type of ladyfingers (which I found in the cookie aisle) rather than the soft type (which were in the bakery section).
I used a berry blend fruit juice (100% juice). Try to pick something with a lot of natural fruit flavor (i.e. not Hawaiian punch), since the flavor of the juice will come through in the end product.
Feel free to use whatever combination of fruit you like: various types of berries, peaches, etc.
