Bourbelier de Sanglier
First you must put in boiling water, and take it out
quickly and stick it with cloves; put it on to roast,
and baste it with a sauce made of spices, that is,
ginger, cinnamon, clove, grain, long pepper and
nutmegs, mixed with verjuice, wine, and vinegar,
and without boiling use it to baste; and when it is
roasted, it should be boiled up together.  And this
sauce is called boar’s tail, and you will find it later
(and there it is thickened with bread: and here, not).
