Step 1 Sprinkle a few grains of salt in bottom of egg cooker. (Salt attracts microwave energy and will help to cook eggs evenly.) Break egg into egg cooker. Pierce yolk and white with fork four or five times to bottom of egg cooker. (Piercing is necessary to prevent "exploding" during cooking.) Place lid on cooker base, lining up notches. Twist to secure. Place in microwave.
Step 2 For Soft-Cooked Egg: Microwave on High (100% power) for 30 seconds, or on Medium (50% power) for 50 seconds. Let stand for 30 seconds before removing lid. If still undercooked, turn egg over in cooker, cover and microwave for another 10 seconds, or until cooked as desired.
Step 3 For Hard-Cooked Egg: Microwave on High (100% power) for 40 seconds. Let stand for 30 seconds before removing egg from egg cooker.
