If you manage to get hold of truffles the best way to keep them for two or three days is to pop them in a sealed jar with eggs or pasta, they will impart some of their flavour into the dried material or through the egg shells. Years ago Paul Levy, the head Foodie, organized a truffle hunt all over the country and many people sent in specimens. To keep them until all the participants could be gathered together for a feast the truffles were stored with rice. The first course of our truffle feast was simple boiled rice balls that were delicately flavoured with the truffle scent. They were terrific.
