Preheat oven to 180C.
Cream the butter, chili paste and sugar until light and fluffy.
Add the egg white, and emulsify that.
Add the flours, ikan bilis powder and salt, until it comes to a dough. Do not overmix.
Stir in the nuts.
Shape them into 1/2 tablespoonful balls.
Egg wash with the egg yolk (add a few drops of water), and place an ikan bilis on top. Sprinkle coarsely ground salt over cookies if you like the rough texture like the ikan bilis with nasi lemak.
Leave the egg wash to dry.
Egg wash a second time.
Bake for 12 minutes on a high shelf.
