Here you can find truffle butter, truffle oil, truffle carpaccio and way more. The more common black summer truffle, present in Umbria, is harvested from May to September. If too little, add a bit of more. In a medium saucepan, sweat the shallot and black truffle in just a little olive oil over low heat for 3 minutes. It looks a bit of like some intergalactic critter from the cantina scene in Star Wars, with tentacles and tendrils snaking around. Relish in Chinese star anise, paying homage to the forbidden inexperienced absinthe of days long past.
