STEP1. Place 100 to 200 grams of calcium oxide lumps in one of the aluminum pans. The amount depends on the size of the pan.
The calcium oxide should form a single, tight layer on the bottom of the pan.
STEP2. Add 25–100 mL of water to the calcium oxide (a little practice will help determine the right amount of water).
STEP3. Stir the calcium oxide and water with a stirring rod.
STEP4. Add a small amount of cooking oil to the second pan and place it directly on top of the calcium oxide in the first pan.
STEP5. When the second pan and cooking oil seem to be getting hot, break open a small egg into the top pan.
STEP6. Cook the egg to order.
