The best thing about this recipe is that it does not require the poaching in a water bath or bain-marie that you find in classic pâté and parfait recipes. Actually, make that the second best thing, the most important thing you need to know about this parfait is it is delicious, absolutely delicious. It is easily adapted, and you can fancy it up a little up by substituting duck livers for chicken and adding extra flavours like orange peel, tarragon, and Cointreau.
