Pickled butternuts

These should be picked when tender enough to be pierced with a needle. Cover with very strong brine and keep the nuts in this for three days; drain and recover with brine. At the end of three days drain again and leave in fresh cold water for six hours. Bring to a boil a gallon of vinegar in which you have stirred a cupful of sugar, two tablespoonfuls, each, of whole cloves and peppercorns, a tablespoonful of allspice and eight blades of mace. Boil for ten minutes, pack the nuts in a crock and pour the scalding vinegar over them. At the end of three days drain off the vinegar, bring it to the boil, and pour it again over the nuts. Cover and set aside for six weeks before eating.
