Read the mussels carefully and throw away all opened mussels. Brush the mussels thoroughly under running water and remove the "beards". Drain the mussels. Peel and halve the onions and cut into strips. Peel garlic and dice finely. Peel and wash the carrots and cut them into sticks. Clean, wash and cut leek into fine strips
Heat the oil in a pot. Fry onions, garlic, carrots and leek in it until transparent. Season with salt and pepper. Add peppercorns and laurel.
Add white wine and bring to the boil. Add mussels and cook covered over low heat for 8-10 minutes. Arrange mussels with stock (throw away the unopened mussels). Delicious with baguette bread
