Combine cream cheese, chèvre, yolks, crème fraîche, thyme, Parmesan and Gruyère. Stir in green onions and salt and pepper.
Combine cornstarch and hot water.
Have ready two damp tea towels to keep the wonton wrappers and finished wontons from drying out. Take out one wonton wrapper and brush the perimeter of the wrapper with the cornstarch mixture. Put about 1 teaspoon of the chèvre filling in the center. Fold one corner of the wonton over to the opposite corner to form a triangle. Press edges together. Then bring opposite corners together and press together. Fry in ½ inch hot oil until golden brown on all sides. Serve hot. Makes about 3 dozen.
