In a large bowl combine crab, celery, onion, hard boiled eggs, chili sauce, and parsley. Mix well and refrigerate.
To make the puffs – Bring 1 cup of water to a boil, add 1 stick of butter and stir until melted. Slowly add flour, a little at a time until the dough forms a ball. Allow the mixture to cool. In a separate bowl beat 4 eggs thoroughly. Stir beaten eggs into flour mixture, mix well.
Preheat the oven to 400 degrees. Grease a baking sheet and drop flour/egg mixture by the teaspoon full onto the baking sheet. Bake for 15-18 minutes. Remove from oven and allow the puffs to cool.
Slice each puff in half and fill with the crab mixture.
