Frozen dessert base
Hi there, I'm making some Whisky Mac ice cream (whisky & sweet ginger) for Burns Night, but I want to use it as a topping on a base of some kind. But the base will need to be edible pretty much straight out of the freezer (the ice cream only needs 10-15mins to soften).
So what could I use for the frozen base? Am thinking about sponge or sponge fingers, possibly soaked in something to soften them up; or crushed biscuits/shortbread, possibly bound together with something like condensed milk; whole shortbread; or some kind of oaty-flapjack thing. Probably 1cm thick or so.
Given that I don't want to break people's teeth when they bite into them it, what would be the best base?
