Tip: Poached eggs can be made up to 1 hour in advance. After poaching, plunge the eggs into a large bowl of ice water until completely cold, about 2 minutes. Remove the eggs to a sheet pan sprayed with nonstick spray and refrigerate until ready to use. Once ready to serve, bring 3 inches of water to a simmer in a medium pot, plunge each egg in one at a time and cook until just heated through and yolk is runny, about 20 seconds.
