Quickly rub the lard, the butter, the egg, the sour cream and the salt into the flour, then briefly knead into a dough; wrap in plastic and chill for 30 minutes.
Roll out the dough to the thickness of a knife-back, and line shell-shaped or small muffin molds with it.
Fill the lined molds with dried beans or rice (blind baking), so they don't puff up while baking.
Pre-bake at 180°C for 15-18 minutes, then remove the beans/rice, and bake empty for a few more minutes, until the pastry is cooked through and golden.
Meanwhile make the sauce: make a light roux from the butter; when it's nicely golden, stir in the spices and the paprika, and fry briefly together.
Add the broth to make a thick sauce, then add the cream.
Stir in the chopped veal roast, and simmer together over low heat for a few more minutes.
Remove the dried beans from the baked pastry shells, fill them with the warm veal ragout, and serve immediately.
