I'm living in Switzerland at the moment. I've just come back from a short holiday and realise I've left some milk in the fridge.
The top oddly has two dates. One marked a which was yesterday and one marked b which isn't for another week.
Knowing that swiss milk tends to be nuclear and last a while I tried the milk and...it does seem a bit off. The water and the solid have seperated slightly in some places. It doesn't smell but it does taste odd.
I think it's fair to say I shouldn't use it. I should do without milk for a day.
However the question remains: what are these two dates?
I guessed best before and use before but that seems wrong.
