How to make
Boil the duck hearts, until they're almost cooked in lightly salted water.
Strain them and dip them in the marinade from the spices.
They are left like this for 1 hour, so that they can absorb from them.
Then cook them on a grill, which need to be greased with bacon.
Serve the beer appetizer warm.
The grilled duck hearts are very tasty.
