Step 1: Soak bird's nest for some time first (different types of bird's nest need different time of soaking), the water should cover the whole bird's nest so that it can absorb maximum water content. Refresh soaking water once or twice during soaking. Typically house bird's nest (white and golden) needs soaking for 3-4 hours and cave bird's nest needs 10-24 hours.
Step 2: Use tweezers to remove the feathers and rinse the bird's nest several times. Tear off the bird's nest tissue and wash away the impurities with running water.
Step 3. All types of bird's nest should be prepared with indirect heat (i.e., stewing or steaming). The best is to use a double cook-boiler. Typically house bird's nest (white and golden) needs cooking for 15-20 minutes and cave bird's nest needs cooking for 1-2 hours.
