Boiled Eggs

Ingredients

Directions

Put the eggs into boiling water and boil for 3 to 5 minutes depending on desired doneness.
For hard boiled eggs, boil for at least 20 minutes.
After cooking, place eggs in cold water until ready to use.
For poached eggs, break eggs into boiling water with a little salt and lemon juice.
Simmer until the white is set, then carefully remove and drain.
For scrambled eggs, mix eggs with milk, pepper, and salt.
Melt butter in a saucepan, add the egg mixture, and stir until just set.
Serve immediately on buttered toast.
