bakery in Krakow that makes pastel de nata?
I doubt that any bakery in whole Poland makes them..
But I have found a recipe, reportedly the tartlets do not differ from the originals.
What you need is: (ingredients for about 8-12 pieces)
300ml of milk
1 vanilla pod
pinch of cinnamon
100g of sugar
2 tablespoons of cornflour
1 sheet of puff pastry
Beat the eggs thoroughly with milk, the pot with milk set on low or medium heat. Add grains from the vanilla pod, cinnamon, sugar and the flour reconstituted with a bit of milk. Stir vigorously to prevent from any lumps until the mass clearly thickened and will remind a thick pudding. Once that happens, leave it it to cool. When the mass is in ambient temperature, lay it down to fit with French pastry-lined muffin tins. Bake at 180C for about 15 minutes.
I hope the translation makes sense ;)
