I took out a frozen milk last night and put it in fridge to thaw. This morning it wasn't complete defrosted so I left it at room temp as I needed it this afternoon. Turns out I never so I asked my partner to put it back in fridge but he forgot. Does it need throwing or can I use it tomorrow? It will have been left in fridge overnight and then left at room temp at 12-11pm (it was still frozen a bit)
