In a fit of nostalgia, I persuaded my mum to make karelian pastries - little mocassins of thin rye dough filled with rice or potato, topped with munavoi (boiled egg mashed with butter). As it's hard to buy them in UK (I got hold of some at a recent Finnish Christmas market), it's good to know how to make them. Mum remembered them being really hard to make, but gave it a go.
Instead of potato, you could use a milk rice porridge (which I remember as being nicer, but my mum prefers potato and it's easier to do).
The dough is cut into little balls and then rolled out into circles. Fill centre with a thin layer of the filling, then fold in the pastry from one end, making a number of little decorative crimped pleats (not as difficult as we'd thought to make the traditional mocassin shape, but even easier to make round ones).
Baked in a very high oven (one recipe suggests 300°, basically as hot as the oven will go) for about 12-15 minutes, the filling will be slightly browned in parts). When it comes out, the pastry is ridiculously hard. You soften it in melted butter (we used butter melted in boiling water, some people also add milk), brush or dip them, then pile them on top of each other so that they soften.
