How often have you picked up a bottle of milk and realised -- after a quick sniff test -- it's funkier than it should be? We've all been there.

Cook book author and former Food in a Minute host Allyson Gofton looks at different ways to salvage foods that are nearing an end, and offers up a recipe for Irish soda bread using that spoiled milk you were going to throw out.
