Here's Pavel Linhart's recipe for Smaženice:
100 g of butter, oil, or pork fat (for frying).
1 large onion, diced.
500 g of mushrooms (bolets, champignons, etc.), cut into 1-2cm cubes.
2-4 eggs, depending on mushrooms; it should be a dish mainly from mushrooms (e.g., 2-4 eggs / 500g of mushrooms)
pinch of salt
pinch of pepper
1 tsp to 1 Tbs caraway seeds (to taste--Pavel advises "it is hard to overdose caraway seed, do not hold back!'")
In a frying pan, warm the butter, oil, or pork fat and fry the onion until it's soft and glassy. Add the mushrooms, caraway seeds, salt and pepper. Cover with a lid, stirring occasionally until mushrooms are well cooked (10-20 min). Mushrooms will release water when cooked but if it is not enough and the mushrooms begin to stick to the pan, add a little water. When mushrooms are cooked add whisked eggs and stir constantly until they harden up.
Serve with bread or garlic bread, or with potatoes boiled in salty water with 1 Tbs of caraway seeds.
