Crush the camembert roughly with a fork and knead with the butter. Season with salt and cayenne pepper. Halve the mixture. Wash parsley, dab dry, remove leaves and chop finely.
Mix one half of the cheese mixture with parsley and the rest with paprika powder. Remove the rind of the gouda slices and cut the slices to the size of the pumpernickel slices.
Spread 3 slices of Gouda with cheese-parsley mixture. Place the pumpernickel slice on top. Then spread with the cheese-pepper mixture and cover with the remaining cheese slices. Chill for about 30 minutes.
Cut each cheese-pumpernickel piece into 9 pieces and put 1 wooden skewer into a cheese petit-four. Garnish as you like with herbs, cherry tomatoes, gherkins, grapes and mini-corn. Makes 27 pieces.
