Can you boil an unopened can of sweetened condensed milk?

Boiling an unopened can of sweetened condensed milk can be dangerous as it can cause the can to explode due to the buildup of pressure inside. The high temperature can cause the milk to expand and create excessive pressure within the sealed container, leading to a forceful rupture.

The sudden release of pressure can result in the can bursting open and expelling hot condensed milk and can fragments at high speed, posing a serious safety hazard.

Instead, to use sweetened condensed milk in a recipe, you can place the unopened can in a pot filled with water and bring it to a simmer. This method allows the can to heat gradually and safely, ensuring that the contents remain intact.

Remember always to follow the manufacturer's instructions for safe handling and preparation of food products, especially when dealing with sealed or pressurized containers.
