Mistake: Cracking eggs on the rim of a bowl.
Feel free to get cracking, but do so away from the vessel that will hold all of your raw ingredients. “Cracking the eggs on the edge of the bowl may get some shell in the recipe—thereby contaminating all the ingredients,” Beckman says.
Plus, you may spread some white or yolk residue onto the outside of the bowl that can drip down to the countertop.
How to fix it: Tap the egg on your counter, then open it into a small, separate bowl. Check egg for quality and add then add it to the larger bowl. Immediately sanitize the counter.
