Wikipedia says “A legend has it that the Austrian Emperor’s perfectionist cook decreed that it should be possible to read a love letter through the strudel paste”… Well, now it’s quite difficult to find a love letter… it’s something that now sounds really “vintage”. But yes: the paste I do is stretched really really thinly: only the lemon zests I usually add could make difficult the lovable reading!
And the Meliga biscuits (a typical Piedmont biscuits), that I use instead of the breadcrumbs, give to my strudel a North-Western-Italy personality to this sweet.
Unfortunately here in London is not so easy to find Russet Apples, but with Bramley you can have a quite good result. Instead Meliga biscuits are easy to find online (waiting for the new opening in London) on Eataly.
