Option 1: Remove the labels on the cans and cook them for about 2 hours and 30 minutes on the boiling water in a pan with cover. It is important that the level of the water is higher than those cans. The longest it takes, the firmer the consistence to be.
Option 2: Open those cans and pour the milks into the cooking pan. Cook and stir them often until it becomes firm and the colors become golden light brown like a caramel color.
6. Option 1: Take up those cooked cans and let them cool down before you open them.
Option 2: Pour the cooked condensed milk into the pie form (which you have already the baked crushed biscuits on the bottom) while it is still hot so it is easy to spread it. Or it is also okey if you want to cool it down first before putting it onto the pie crust.
