Truffle Perlage - Pearls of Winter Black Truffle Juice (T.melanosporum). The TRUFFLE PERLAGE® is a very innovative product invented by Tartulanghe. The Truffle Caviar is made from the black winter truffle juice, which is obtained directly from the fresh truffle during its cooking. This tasty juice is then reduced in small pearls through a very sophisticated technique called “esterification”. We obtain small pearls with the taste of the truffle and the same color and texture of the caviar! Use tips: try it on crostini bread or blinis and use it to garnish fresh cheese, hams and foie gras, fish carpaccio and fillets, soups and vegetable creams, cheese fondue, eggs potatoes, meat fillets and all dishes that combine with the truffle. Ingredients and Allergens: Ingredients: Black winter truffle juice 50% (Tuber melanosporum Vitt., water, salt), water, squid ink, thickener (sodium alginate), salt, flavor, acidifier (citric acid).
