Hernepirukas (pea pastry)

Instructions

1. Cook the peas in unsalted water for 45 minutes to 1 hour, until very tender, then mash them.
2. Meanwhile, rub the flour with the cold diced butter, then add the egg and water and knead to a supple dough.
3. Wrap the dough in cling film and chill for 30 minutes.
4. Fry the bacon and sliced onion until golden, then mix them into the pea mash and season.
5. Preheat the oven to 200°C and roll out the pastry to 3 mm thick.
6. Cut out 12 cm discs, fill them with the mixture, fold into half-moons and seal the edges with a fork.
7. Place the pastries on a tray lined with baking paper, brush with beaten egg and bake for 25 to 30 minutes, until well browned.
