Remove the cooked rabbit meat from the bones, and grind it.
Add the soaked, squeezed-out bread roll, the butter and the eggs, pound the whole thing finely (in a mortar or food processor), then pass through a sieve.
Salt it, mix in the finely chopped mushrooms, the cubed bacon and the cubed roasted goose liver.
Line a terrine or porcelain mold with bacon slices, and fill it with half of the mixture.
Layer the hard-boiled egg slices on top, then cover with the other half of the mixture.
Cover the mold, and cook/bake it in a water bath (steamed) for about 2 hours, until the mixture sets.
Let it cool, chill overnight, and decorate and coat the top with melted aspic.
Serve cold, sliced.
