Can you use tin of black treacle best before end 2010?

Using a tin of black treacle with a best before date of end 2010 is not recommended, as it is well past its suggested date. While some canned goods can last beyond their best before dates if stored properly, the quality, flavor, and safety may be compromised. It's best to check for any signs of spoilage, such as off smells or unusual textures, before considering consumption. When in doubt, it's safer to discard it.
