Line a large baking sheet with greaseproof paper or sprinkle it lightly with flour. Set aside. Combine the cheeses in a bowl, then add the cayenne and beaten egg and mix well.

Place one wonton wrapper at a time on a board. Brush the edges with egg. Spoon a little filling in the centre; pull the top corner down to the bottom corner, to make a triangle.

Transfer the filled wontons to the prepared baking sheet.

Heat the oil in a deep-fryer or large saucepan. Slip in as many wontons at one time as can be accommodated without overcrowding. Fry them for 2 - 3 minutes on each side or until the fritters are golden. Remove with a slotted spoon. Drain on kitchen paper and serve at once.
