What is the correct action for leftover garlic margarine?

The correct action for leftover garlic margarine is to discard it each night. This practice is rooted in food safety guidelines, which ensure that perishable items are not kept beyond their safe storage period. Garlic margarine, while it may seem stable, can harbor bacteria if stored for extended periods. By discarding any leftover product nightly, you minimize the risk of foodborne illness and maintain the quality and freshness of the ingredients served to customers.

Storing it in the fridge may seem like a viable option, but it does not ensure that the product will be safe to use the following day, especially once garlic is mixed with other ingredients like margarine. Restocking for next day or using until finished could lead to the same potential issues of spoilage and safety, contradicting the preventive measures necessary for managing food products in a restaurant setting. Therefore, the most responsible choice is to discard leftover garlic margarine each night.
