Hard-boil the eggs, and when done remove the shells and cut the eggs into halves lengthwise, keeping the whites whole. Remove the yolks, press them through a sieve, add to them the cream, half the salt and a dash of cayenne. Mix thoroughly and fill into the whites and arrange them neatly on a granite or silver platter. Put the butter into a saucepan, add the onion and flour, then the stock or cocoanut milk, and the mushrooms; stir, until it boils, add the remaining salt and pepper; take from the fire and add the parsley. Pour this over the eggs on the platter, dust thickly with bread crumbs, run into a quick oven until brown.
