Use the Goldfish Egg Separator to speed up the process of removing egg yolks when baking. Squeeze the fish, place the mouth over the egg yolk and release... the goldfish sucks the yolk up into its belly. When you want to use it or toss the egg yolk, simply squeeze the egg separator tool to extract the yolk. Smooth silicone material is soft to protect the yolk sac. Silicone is an incredibly flexible, non-stick material that is known for being stain-resistant, heat-resistant, and dishwasher safe. This makes it easy to clean and reuse your favorite new kitchen baker tools over and over again without concerns of wear.
